One number can set off the whole board. Trigger satisfying chain reactions, build huge combos, and solve Sudoku in fewer moves. Arcadoku turns classic Sudoku into a fast, tactile arcade puzzle. Place the right number and watch the grid react. Completing a row, column, or 3x3 box can fill its final open cell automatically. That placement can complete another group, then another - turning one smart move into a satisfying chain reaction. THINK AHEAD. START THE CASCADE. The goal is still pure Sudoku: fill every row, column, and 3x3 box with the numbers 1-9. But in Arcadoku, how you solve matters. Find moves that set the board in motion, build bigger combos, and finish each puzzle in fewer moves. STAY IN THE FLOW When a board is complete, there is no results screen breaking your rhythm. The grid celebrates with a colorful pixel-art surprise, reloads, and brings in the next puzzle. FEEL EVERY COMBO Numbers pop into place one after another. Sound, haptics, animation, and escalating combo moments make a clever cascade feel as good as it looks. LEARN AT YOUR PACE New to Sudoku? A short, optional tutorial teaches rows, columns, boxes, and Arcadoku's chain reactions by letting you play. Already know Sudoku? Skip the basics and jump in. PLAY YOUR WAY • Choose Easy, Medium, or Hard • Discover a collection of pixel-art celebrations • Continue from one prepared board to the next • Play in English, Spanish, Brazilian Portuguese, German, French, Russian, or Japanese ABOUT MOVES Entering a number uses one Move. Moves recharge over time. You can also earn refills through optional rewarded ads. An optional monthly Unlimited subscription removes Move limits and the need for refill ads. A one-time Supporter purchase increases Move capacity and speeds up recharging, but does not unlock unlimited play. Whether you chase a cleaner solve, a longer cascade, or one more perfect move, Arcadoku gives Sudoku a playful new rhythm.
