No guessing. Just logic.
Crodoku is a calm logic puzzle with crocodiles. Place one crocodile in every pond, every row, and every column, and keep them apart: crocodiles can't touch, not side to side and not corner to corner. Every board has exactly one solution, and logic alone gets you there.
Meet Bazyl, a grumpy young crocodile who loves his sunny spot and his personal space. A short tutorial shows you the rules, and then the swamp is yours.
• 3,000 levels on boards from 5×5 to 10×10, each with exactly one solution
• Four habitats (the Nile, Everglades and the Caribbean, Asian rivers and mangroves, the Amazon), then the Endless swamp
• Swamp Daily: three new puzzles every day (easy, normal, and hard), a streak to keep, and an archive of the past week
• A Big Bask every 10 levels and a Swamp boss every 50
• Not sure what's next? "Why?" shows you on the board, step by step, where the next move comes from, "Mark" marks the cells the next step is about, and "Reveal" places a crocodile
• The Species album: discover 12 kinds of crocodilians, with facts and their IUCN status
• Earn Fireflies and spend them on skins, accessories, swamp decorations, boards, app themes, avatars, and frames
• Daily and weekly missions with chests. Chests come only from missions, never for money or ads
• Three lilies per level instead of lives, and in the first levels mistakes are free
• Plays offline. Colorblind mode, high contrast, screen reader labels, and keyboard controls
• In English, Polish, Spanish, French, German, Italian, Brazilian Portuguese, and Ukrainian
Crodoku is free thanks to ads. No Breaks is a one-time purchase: no ads between levels and none at the bottom of the screen. Rewarded ads stay optional.
