The game is based on the principle of the puzzle "15". Moving the chips you need to collect them in order. The game ends when all the chips in all layers will be in ascending order, starting with the upper left corner of each layer. The field sizes are initially available in width and height from 3 to 5 and the number of layers 1. With a width and height of 3, you can set the number of layers 2. Control: When you touch and further move one finger to the screen area outside the chip field, you can twist the chip field. Chips move by touching them with one finger and moving in the desired direction. You can move only those chips that do not have a neighbor in one of the directions. You can shift the layers. To do this, it is necessary to simultaneously touch two chips of one layer with two fingers and slides in the desired direction until the layer is fixed. Similarly, the layer returns to its place. Important! In the moved layer, you can not move chips! You can extend the application's capabilities with the built-in purchases: - "All dimensions" - limits on the size of the field are removed.

Find the dogs. Crack the case. Detective Doku is a cozy, all-ages brain game that combines logic puzzles with gentle village mysteries. You're the new detective of Villebrume, a warm little village where the winning pie goes missing, the festival bell falls silent, and the fountain turns pink overnight. The kindly mayor needs your sharp eye. Ready? HOW TO PLAY Each level is a colourful grid puzzle in the beloved "Queens" style: - Place one dog per row, column and colour zone. - No two ever touch, not even diagonally. - It's all pure logic. Tap to rule out a cell, double-tap to place a dog. During case investigations, evidence is revealed at key milestones as you clear boards. CRACK THE CASE Collect the clues across a chapter, then head to the deduction board and name the culprit from the village cast. Follow the trail — a blue ribbon here, a muddy boot print there — and close the case! REBUILD THE VILLAGE Villebrume has seen better days. Spend what you earn restoring it, one landmark at a time — the Town Square, the Perrin Farm, the Shopping Lane, Villa Rosemonde and Lighthouse Beach. Every repair brings a heartfelt thank-you from the villager who calls it home. WHY YOU'LL LOVE IT - 8 charming mysteries, plus a puzzle ladder that never runs out, with fresh challenges for as long as you want to play. - 100% logic. No guessing: every puzzle has one solution you can always reason out. - Helpful, explained hints when you're stuck — they tell you why. - Choose your pace: the main puzzle ladder is untimed. Case, daily and competitive modes can add timers, while some modes use limited hearts or recharging energy. No violence. - A lovable cast of recurring villagers — the baker, the florist, the clockmaker and more. - A whole village to restore across 6 chapters, with daily rewards along the way. - Climb the friendly leaderboard — or just take your time. It's your case. - Play in your language: fully translated into 22 languages. - The relaxed puzzle ladder works offline; some case, social and reward features need an internet connection. Whether you love Queens-style logic puzzles, sudoku-style brain teasers, or cozy detective stories, Detective Doku is your daily dose of feel-good deduction. Find the dogs. Crack the case. — Privacy Policy: https://www.2cm.studio/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
