DinoDoku
DinoDoku
Three rules. A thousand levels.
A quiet Star Battle–style logic puzzle with dinosaurs. No timers, no energy meters — just deduction, offline on your phone.
A calm deduction game — not another number grid
This site is a preview funnel. Play one sample level in the browser. The Android app ships all 1,000 machine-verified boards offline, with assists, skins, and an honest freemium path.
One dino per color, row and column
Place dinosaurs so each color region, each row, and each column holds exactly one — and no two may ever touch, even diagonally.
- 1 Dino per color
- 1 Dino per column & row
- Dinos cannot touch
Mark freely. Commit carefully.
Cells cycle empty → marked → dino. Marking never costs a life. Only an illegal placement does. Finish with three lives for three stars — a best result never downgrades on replay.
Ten chapters from Hatchlings to The Long Night
Boards from 5×5 to 9×9, each verified to have exactly one solution. Difficulty ramps inside every chapter — no dropdown, just a ladder you can climb at your own pace.
Collect eleven dinosaurs
Brontosaurus is free by default. Clear levels — or use an optional rewarded unlock — to gather more skins. Premium opens every dinosaur at once.
