Every row, every column and every colored region hides one little duck. Can you find them all? DuckDoku is a number-free logic puzzle based on the classic Star Battle, also known as Queens. It blends Sudoku-style elimination with Minesweeper-style deduction. Learn the rules in seconds: every puzzle has exactly one solution, and you can always reach it by logic alone. No guessing required. SIMPLE RULES, DEEP THINKING • One duck per color: the board is split into colored regions, and each region holds exactly one duck • One per line: every row and every column also holds exactly one duck • Personal space: ducks don't like crowds, so no two can touch, not even diagonally • Three hearts: double-tap to place a duck. A wrong move costs a heart, and you get three per puzzle, so guessing won't get you far A REAL JOURNEY Travel with the ducks through 18 themed worlds, including Seasons, Solar System, Oceans, Zodiac, Into the Deep and Chess Pieces: 183 chapters and 9,940 verified puzzles in all.

Verdict
The clearest difference is ads: DuckDoku at none against Fishogram's shown. DuckDoku also leads on ratings volume (5 vs 1) and iOS requirement (15.0 vs 17.0). Fishogram's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 2 days vs every 5 days). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. DuckDoku sells 4 one-off in-app purchases and Fishogram sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for DuckDoku against 5.0 for Fishogram. That said, the two scores are not equally well evidenced: DuckDoku has 5 ratings behind it against 1, so its average is the more settled of the two.
DuckDoku ships an update every 5 days, Fishogram every 2 days. Both last shipped on November 6, 2026.
