HamamDoku
Think and place the roaches
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
HamamDoku is a logic puzzle. Place the roaches on a colourful board: one in every row, one in every column, one in every colour, and none of them may touch, not even diagonally.
Three mistakes end the run. How far you get is your score. No timer, no rush.
HOW TO PLAY
• Tap an empty square to cross it out. Crosses are free, mark as much as you like.
• Tap the same square twice to place a roach. It is the only move that can cost a heart, so you have to ask for it twice.
• Drag your finger to cross out a whole run of squares in one go.
On first launch a short tutorial shows you how, finger and all.
EVERY BOARD IS SOLVABLE BY LOGIC
The game solves every board before you see it. No guessing, no luck, only reasoning. Boards grow from 5x5 to 10x10 and the levels never end.
LAST HEART? ENTER THE DIVA
Down to your last heart, the Diva Roach takes the stage and the board is hers. On the third mistake the sergeant grabs the radio and lights your mistakes up with rockets. When your hearts run out you can watch an ad once per run to carry on where you left off.
FREE ROACHES
Stuck? Use a free roach: it places a roach on one of the right squares. Three are a gift on first launch, and you earn one more every 50 levels. You can also get more by watching an ad or buying one.
RANKING
Compete with everyone in the weekly season; the board resets every Monday. Your best level stays on the all-time board.
