Slimedoku - Pure Logic Puzzle

Slimedoku is a logic puzzle played on a grid of colored areas. Every row, every column and every color area needs exactly one slime, and two slimes that touch, even diagonally, merge into one. Each board has been checked so you can solve it all the way through by deduction, without guessing.

There are three moves. Tap a cell to mark it with an X, double-tap to place a slime there, and drag across several cells to X them out in one go.

- 150 built-in levels on boards from 4x4 up to 10x10, and the levels keep going after 150
- The first time you play, a 4x4 practice board walks you through the moves and rules step by step
- Each level gives you 3 hearts. Placing a slime on a wrong cell costs one, and when they are gone you can retry, or watch an ad to continue once per level
- A hint highlights a cell you can figure out right now and explains why in a speech bubble. Reveal fills in one correct cell for you, up to twice per level
- You start with 3 hints and 2 reveals, and every 10 levels you clear adds 1 more hint
- Clearing level 10 opens the Daily Puzzle. A new 7x7 board arrives at midnight UTC, and everyone gets the same board on the same date. Solving it day after day builds your streak
- Place correct slimes back to back without a mistake to build a combo and a bigger score. Best scores are kept separately for each level and for Daily Puzzles
- Collect 7 characters: Classic, Frog, Cow, Wizard, Rabbit, Ghost and Shark. They unlock as you clear levels and keep your streak, and the one you equip shows up on the board
- Characters on the board blink now and then and smile when they land on the right cell
- No time limit, and no internet connection needed to play
- Choose English, Korean or Japanese, and turn music, sound effects and vibration on or off separately in Settings

Slimedoku contains ads. Starting at level 11, a full-screen ad may appear after a level ends. Watching a rewarded ad to the end gives you 1 hint or 1 reveal, a continue, or a restored streak, and loading ads needs an internet connection. There is no sign-up, and your progress is saved only on this device.
