This game is a masterpiece. Good job; loved trying to figure out how things were built and positioned.

(+2)

I found it very fun to slowly learn the rules for how everything is positioned and placed in this game, but after playing this every so often for months now, I realized there was one I missed, which inspired me to do a writeup on all the little enemy patterns and hidden things in the game here. Decode any of the entries with ROT-13 if you're struggling (or just curious to learn more):

The updated version of this game download - i1tchupdate.pages.dev (copy/paste) 

Love it! Great mix of minesweeper with Magic Tower, and leaving the player to infer the rules of the game is the cherry on top!

(+2)

Found a bug. In the top-left area there's a gargoyle facing right, but there's a slime directly next to it where its pair should be. Looking at the source code, the algorithm that places each entity uses a "happiness" method, which has a very high chance of respecting the pattern but doesn't actually enforce it, which can lead to unexpected scenarios like this one.


Cool

Awesomesauce game! Managed to beat the dragon for the first time after a solid few days of coming back to the game lol.

Found a clone of your game

https://cnava.itch.io/dungeonsweeper

report it and get it removed? they also published to steam

ai rip-off

Dear developers, I love your game very much, please make an Android version, it's a great time-killer ❤️

I got all stamps!!!  Great game!!  I love minesweeper!!!

yohohoo, finally!


great game

Brilliant game bro i love it!

Thanks GameGrumps for getting me out of the whiteout survival time wasting simulator by sliding me this game.

(+3)

After so many tries I finally did it!! :)

Loved it! I had to stop watching the GameGrumps' video on it halfway through in order to come play it myself, and then I didn't stop until I got a perfect round. Great game, I'll probably come back to do the other achievements soon.


(+4)

This took forever to do and I do not recommend it :)

(+1)

I only just realized that meant you did all three of those in the same run and now I've gotta try it

Update: You're right. that hat trick was ROUGH.

Same, needed a strategy reset from making max score runs to trifecta-runs.

hey everyone! great game and fun to play, but any tips? I kinda suck and I learn a bit but I keep having to gamble to die because i lost all my hearts and trying to get a heart.

Honestly, I'd say just experiment, and try and look for the patterns in how the monsters show up - many of the monsters have specific behaviors and spawn  in certain ways. It's not 100% guaranteed, but it means that if you see a certain pattern on the board, you can guess if there's a decent chance a certain monster will be nearby. I've figured out patterns for the following monsters:

egg, gargoyle, beholder, minotaur, purple slime, slime wizard, romeo & juliet, mine king, gnome

All of the above monsters show up in specific ways, if you can discover how. Once you learn their patterns, you can make educated decisions about what the monsters do and what squares they're likely to be in!


(if anyone else figures out any patterns for rats, bats, skeletons, green slimes, or gladiator ,let me know - these ones still seem random to me)

(+1)

@GameplayerMcGee I assume by "gladiator" you mean the level 7 monster with the shield. There's definitely a pattern, you just need a ton of games to see it. There's always 4 of them, one per quadrant of the board. The grid is 13x10 so each quadrant ends up being roughly 6x5, excluding the dragon's column. After observing countless runs (you can just click the dragon early to die instantly and see the whole grid), I've never seen one spawn on the dragon's row either. So they basically avoid the central column and the dragon's row entirely.

One detail that's really subtle on the devs' part: each gladiator's shield marks which quadrant they belong to. The center of the shield has a 2x2 yellow square, and one of those four pixels is red. The position of the red pixel inside the 2x2 maps to the quadrant. So the top-right gladiator has the red pixel in the top-right corner of its 2x2, and so on.

About rats, they're not totally random either. Their sprite tells you where the rat king is relative to them. If a rat is facing right, the king is somewhere in a column to its right. If it's facing left, king is to its left. If it's standing upright facing forward, it means the rat is in the same column as the king. And once the rat king dies, all rats switch to that standing pose.

Bats, skeletons and green slimes I haven't been able to figure out either, they just seem to be filler. Their role seems to just be contributing their level to the danger numbers around them. If anyone else spots a pattern there, let me know.

* Each time you die, look at the board, see if you spot a hint or pattern. There are plenty.
* You can count the time until you need a heart scroll by comparing xp row to heart row.
* Save the scrolls as long as possible. A late game scroll is worth a lot more than an early game scroll.
* Bashing walls is an absolute last resort 
* Look at squares, do simple math, check the book to see what monsters are still around.

Yippee :D

what does the gnome even do??

its there for funnies

When you uncover the gnome, it teleports to a random unrevealed empty tile if one exists. Otherwise, you kill it and it drops 9 gold.

Effectively, the gnome represents a 9 gold bonus for revealing every empty tile in the dungeon.

(+1)

So close to max score... I thought I did it perfect, not sure what I missed but I had two walls left to break. I was at 0 health and 17 xp short of the level up to get the full 16 hearts

(+1)

the walls are 3 hits, worth 1 point each

Scam link. Ignore it.

JUST FYI- for the version on dragonsweeper.com: (version 1.0)
the highest score you can achieve on new mode is 357 points, as of this post. 

I'm just now realizing other people are playing a different version from me, so I'm not sure about that version. BUT, for the dragonsweeper.com version - 

The game spawns with a max of 362 points (that is, experience points), which includes 6 wall units (1 point each - they drop a golden ring) and 356 points worth of monsters. This value includes the dragon. There are only enough hearts and experience point level-ups to destroy more than all the monsters, plus one box, for 357 points. Thus, if you play a perfect game, only leveling up when you have completely depleted your heart meter and wasting no hearts, and if you kill the dragon when you have 13 hearts and then finish up killing the remaining monsters plus 1 wall unit, you will have exactly 357 points.


The number of monsters spawned is random so you often will not be able to score this high even if you play a perfect game -- there will often be some rats leftover. But the highest possible score seems to be all monsters, plus 1 wall. It might--MIGHT--be possible to score 1 point higher and destroy TWO wall segments, but I haven't seen this happen after much MUCH play time. 

HOLY SHIT!!!! it's version 1. I usta play the SHIT outa it when it first droped, and I've been playing the update almost every day since it droped in feb '25, but NICE ONE, I've been trying to reember  what ver 1 was like for SOOOOO long. tripple thums up man!

ah, well, i guess everyone else figured out the max score is attainable in the new versions 'cause of egg. Oh well.

Everything about this game is incredible... except for the epileptic hazard in the first two seconds as the game loads.

This shares a lot of similarities to a recently released roguelike on Steam named Grix. Is there any developer connection to this game?

(+1)

I did it! After more than two hours of trying, but I did it! TToTT 

got the lovers survive stamp!

Has anyone been able to acheive the "3 stamp 325 point" run yet? 

@gronken got 319 according to his previous comment, and @KomoMeteor showed us 325 is possible possible.

(-1)

325 for all three is insane, i hate that freaking egg now

Took a fair few attempts but finally got every achievement

(The egg one I kinda cheesed, getting lucky with a magic orb) 

Very very cool game, I really like how it rewards patterns recognition for what spawns near what/in what positions/etc!

What's your best with a full board clear? (minus whatever wall segments are left, naturally)

(+2)

After many months I still enjoy to play this! Today I got six gargoyles from the first orb.

I often try to do the challenge to clear everything with 13 hearts remaining. Does somebody have other challenge suggestions?

Speedrun ?

I've played this almost every day since it came out  about a year and a half ago, so relaxing, so adicive, such a good game. These days it's mostly clear screen as fast as possible, but some of the personal chalanges I've done in the past are: finish without collecting the mine king scroll.  Never use the crystal ball.  Play VERY drunk. Save all slimes. 

1. Speedrun the dragon as quickly as possible (helloyyy has done it in a blisteringly fast 1 minute 44 seconds)

2. Speedrun a perfect game/full board clear (i.e. only level up or grab a heart when you completely run out of hearts, so that you get as high a score as possible) (My best time in version 1.0 was 3:20, haven't tried in new version).

3. Beat the game with any of the 4 achievement stamps (click "next page" on the instruction booklet for an achievement breakdown).

4. Beat the game with 3 of the 4 stamps in a single run.

5. High score or speedrun with 3 of the 4 stamps.

6. Beat the all time high score with 3 of the 4 stamps (judging from the comments, it's _319(!!!!)_ points, without ever touching a rat, egg, or the lovers. But apparently 325 would be the all-time high score for the whole community).

I downloaded the zip and extracted all, but I keep getting an syntax error code when I try to launch it. Any suggestions?

(+2)

Finally! Took an embarrassing amount of tries and time....
Go for the egg by the dragon first, prioritize the mine creature in the corner, and then once you get to the end go: Dragon -> Mimic -> 8 Slime 5 Slime x 5 ->  the rest if you're lucky...

what---why is my version different? I'm playing on dragonsweeper.com. is this not accurate?????

This is a fun one! is it always solvable without guessing?

Not really. It might happen randomly, but you normally need to take atleast a few wild shots. Either way luck is needed. 

(+1)

If you get lucky with the map gen, yeah.

This comment will spoil some things that you could discover on your own, read at ya own risk.

There's a lot of predictable stuff that's neat: 

* Guardians cannot spawn directly on the dragon's axes (as in plural axis) (Guardians are the 7-power guys)

* Only one Guardian spawns per quadrant (Northwest, Northeast, Southwest, Southeast), and every quadrant contains one Guardian

* Rats will face in the direction of the Rat King (until the Rat King is slain).

* Beholders will obscure tiles, but the more obscured tiles you have, the easier it is to know where the Beholder is hiding (as it's just two tiles away in all cardinal directions, one tile directly diagonal; it blocks 12 tiles while it's active). 

* Gargoyles (4-power guys) always spawn in pairs, directly facing each other. Every time you can be certain about marking a 4, there is always at least one other 4 adjacent to it. You can see their facing direction in their sprite, which will show upon either something like the vision orb revealing them, or them being revealed by you killing them.

* There is always a Minotaur (6-power guy) in one of the eight tiles surrounding a chest. There is always a chest in one of the eight tiles around the Minotaur, too. You also can see the Minotaur react to you opening its chest, and, in the event two chests spawn within the radius of one Minotaur, you can actually use that to know that there is a second chest to begin with, and by extension a second Minotaur.

* The Gnome seems to, from my experience, be uncatchable until you have revealed every empty tile.  If something should reveal the tile the Gnome inhabits, the Gnome stands on top until you manually reveal the tile.

* The Mine Lord (10 power guy) always spawns in a corner. No exceptions. This actually means that if you can be certain that the Mine Lord is not in 3 of the 4 corners, you guarantee he's in the 4th, which means you don't need to spend time finding your way over to that corner and can instead just click the corner square on its own.

I've been playing logged in. I also paid and downloaded. How does one play this so it actually tracks the achievements? How do you even run the game after downloading it? There doesn't appear to be a game launcher. 

(+1)

Just spent 4 hours trying to win once. VERY SATISFYING TO FINALLY GET IT.

Amazing game!

(+2)

I saw this game on game grumps and it's super fun. Got all the achievements!
