DinoDoku: Logic Puzzle

DinoDoku is a calm, offline logic puzzle game for Android: place dinosaurs on a colored grid so each region, row, and column holds exactly one dino—and no two may ever touch, even diagonally. Three rules. One verified solution per board. No account required.

Looking for a sudoku alternative without numbers? DinoDoku uses Star Battle–style deduction, not a number grid and not Minesweeper. Prefer a puzzle game that works with no wifi? All 1,000 levels ship inside the app—nothing to download mid-play.

WHAT YOU GET
• 1,000 machine-verified levels across 10 chapters (Hatchlings through The Long Night), boards from 5×5 to 9×9
• Unique-solution guarantee — every puzzle is solvable by pure logic; guessing is never required
• No board timer and no leaderboard — think as long as you need; stars come from careful play, not speed
• Free marking pass — mark cells to reason out loud without losing a life
• Assist tools that keep the puzzle yours — Locate (free), Hint, Clear, and Coordinates
• 11 collectible dinosaur skins and 7 theme packs (Cretaceous Clay free; more with Premium)
• Nest Chest daily reward, Hunt streak, daily quests, Eggs & Clue Bones soft currency
• Offline-first and account-free — progress stays on your device

HOW A BOARD WORKS
Place one dino per color region, one per row, and one per column. Dinos cannot touch — including diagonally. Broken rules cost a life; finish with three lives for three stars. Free hint budgets scale with board size so at least three dinos are always left for you to deduce.

ROARS (START ENERGY — NOT A TIMER)
After the first 10 levels, free players spend a Roar to start a board. Roars regenerate over time (max 5). Premium players get unlimited Roars. Your thinking time on the board is never timed.

NEST CHEST & DAILY QUESTS
Open today’s Nest Chest to keep your Hunt streak. Complete simple daily quests (win levels, use a hint, claim the chest) for Eggs and Clue Bones. Chapter clears and star milestones unlock extra chests.

HONEST FREEMIUM
Free: every level, optional rewarded ads for extras, banner + paced interstitials, limited Roars and hints.
Premium: no ads ever, unlimited Roars, unlimited retries, hints without ads, every dinosaur skin, every theme pack, Nest Chest Egg bonus, and a weekly Hunt streak shield.

WHO IT’S FOR
Players who want a relaxing logic grid, a dinosaur-themed Star Battle / Queens-style deduction game, or a quiet offline puzzle for kids and adults to share—without signing up.
