Released 2026-10-15. 11 updates since release, the newest 2026-10-18.
Newest update: Rat Down (2026-10-18)
- When a player's rat goes off, everyone else sees a big card in the middle of the screen with their name and a portrait of the rat they were wearing.
Earlier update: Hundred A Square (2026-10-18)
- Every square you clear is worth +100, flooded pockets included, and each jump's total floats up over your landing. Going off shows -100 on the spot. The Golden Rat trophy now takes 100,000 lifetime points (was 10,000).
Earlier update: Thinking Rats (2026-10-18)
- NPC rats now head for the edge of the hidden tiles instead of wandering, then sniff and think 25-45 seconds before each jump. They guess blind 30% of the time (was 50%), so they help finish the field without stealing it from you.
Earlier update: Snip Snip (2026-10-18)
- Plant a flag on a tile the numbers prove is a mine and it's defused on the spot: wire snip, +100 points, and the tile turns into a defused mine you can walk on. Flags the numbers can't settle stay up.
Earlier update: Click To Leap (2026-10-18)
- Click any square: left-click leaps your rat onto it, right-click plants or pulls a flag. Click a square that's too far and your rat runs over and leaps as soon as it's in range. Drag with a mouse button to turn the camera. Rats spooked by an explosion recover twice as fast.

- @key_master (maker) replied 2026-10-16: “Thanks for trying the game parc1val! I changed the way the point moves so the rat wont get lost.”
@sunraku · loved it · 2026-10-18 · played 3 min: “Hey bro! You have here a unique game. What I love in this was the concept. You made an openworld minesweeper with rats being the character. It was so cool. You can also add powerups, i don't know if possible though I know that minesweeper has no P.up”
@moypi03 · loved it · 2026-10-18 · played 3 min: “Wow man! I wasn't expecting this to be a Minesweeper-style game hahaha! The exploding rats caught me off guard, and even though I ended up with negative points, I still had fun playing it”
@makeriffic · loved it · 2026-10-17 · played 6 min: “Hilarious and awesome gameplay dude! I find it funny and petty each rat that explodes on impact of a mine lol, poor creatures but very funny gameplay! It elevates the classic minesweeper gameplay lol.”
