Do you want a puzzle app that keeps surprising you, level after level, instead of feeling the same after the first few boards? If yes, look no further than Duko! It's a logic puzzle game with 11 unlockable symbol themes, five grid sizes from 4x4 to 12x12, daily challenges, and full offline play. Introduction to Duko Duko takes the puzzle you already know and gives it a twist: the symbols themselves change as you play. Numbers give way to shapes, hieroglyphs, animals, and emoji, unlocking one by one as you progress, so every new stage feels fresh instead of repetitive. The rules stay pure sudoku - every row, column, and region holds each symbol exactly once. But with hundreds of puzzles spread across five grid sizes and eleven unlockable themes, Duko keeps rewarding you long after most puzzle games have run out of new ideas to offer. Whether you're new to sudoku or you've solved thousands of grids before, Duko's growing collection of themes and sizes gives you a reason to keep coming back. Start simple with numbers, then go as deep as 12x12 hieroglyphs whenever you're ready for the next challenge. Main Features of Duko: Story Mode: Hundreds of progressively challenging puzzles across five grid sizes, from compact 4x4 boards for beginners to epic 12x12 grids for advanced players. Fewer clues over time means more thinking, more strategy, and more satisfaction with every solve. Beat a level to move forward, or replay any finished stage whenever you feel like a refresher. 11 Unlockable Symbol Themes: Numbers, coloured shapes, emoji, Egyptian hieroglyphs, zodiac signs, animals, playing cards, and more unlock naturally as you advance through story mode. No other puzzle game grows and evolves quite like this one, so the classic sudoku formula always feels new. Daily Mode: One new puzzle every day, always ready and waiting. Open the calendar, play today's challenge, and build your streak day after day. Finish tonight or come back tomorrow - your past days stay saved, so you can replay any of them whenever you like. Some Extra Features of Duko: Smart Tools: Hints, lives, undo, notes, and instant conflict feedback help you learn the logic behind every move instead of just guessing your way through a grid. Offline Play: No internet connection needed, ever. Play your way through story mode or daily puzzles on a plane, on the train, or anywhere else a signal can't reach you. Built for Every Player: Portrait-friendly on phone and great on a larger tablet screen, Duko fits neatly whether you have two spare minutes or a full twenty to relax, unwind, and focus. Replay Anytime: Revisit any finished level or past daily puzzle whenever the mood strikes, without ever losing your progress, your unlocked themes, or your streak.
