Bitdoku

Ready to give your brain a playful workout? Bitdoku puts a charming cat-themed spin on Sudoku. Study the board, think ahead, and work out where every cat belongs - one satisfying logic puzzle at a time.

HOW TO PLAY
Place cats on the grid so that each row, each column, and each colored region has exactly one cat. Keep an eye on the clues - and remember, cats can’t touch, even diagonally! Look for patterns, rule out possibilities, and solve each board through careful deduction.

A FUN TWIST ON SUDOKU
Solve cat-themed logic puzzles that reward focus and observation.
Take on a growing series of levels, from learning the rules to trickier boards.
Try the Daily Challenge for another bite-sized brain workout.
Use hints when you need a nudge, or find-a-cat boosts when available.
Enjoy playful cat reactions and satisfying level-completion moments.
Whether you love Sudoku, brain teasers, logic games, or casual puzzle games, Bitdoku offers a fun way to pause, focus, and think a few moves ahead. Pick up a puzzle for a quick break - or stay for one more level.

PLAY PUZZLES, EARN SATS AS AN EXTRA
Eligible level completions may award satoshis (“sats”), tiny units of Bitcoin, when rewards are enabled and available. Rewards are handled through ZBD. Cash-out is subject to ZBD’s account and eligibility requirements, as well as any minimum withdrawal threshold shown in the game. Reward amounts, availability, and terms may vary by location and can change.
