About

Sudora

Read full description

Sudora is five number and logic puzzles in one quiet app. Pick one from the lobby and play — each game keeps its own puzzles, its own records, and its own place to pick up from. SUDOKU Fill the grid so every row, column and 3x3 box holds 1-9 exactly once. Five difficulties, from 45 clues down to 24. NONOGRAM Also called picture cross or griddlers. Use the number clues along each row and column to work out which cells are filled, and a hidden picture appears. Three sizes: 5x5, 10x10 and 15x15. KAKURO A crossword where the answers are numbers. Fill each run with digits 1-9 so it adds up to its clue, never repeating a digit within the same run. Three sizes. CALCUDOKU Each row and column holds every number once, and each outlined cage has to reach its target by adding, subtracting, multiplying or dividing. Three sizes: 4x4, 5x5 and 6x6. 2048 Swipe to slide the tiles. Matching numbers merge and double. Reach 2048 on the 4x4 board, or push for 8192 on the 6x6. ACROSS EVERY GAME • Puzzles are generated fresh and verified to have exactly one solution, reachable by logic alone • Best times kept per size or difficulty • Leave a puzzle mid-solve and come back to it exactly where you left off • A built-in tutorial plays each game out step by step • Works fully offline • No account, no sign-up Five puzzles, one app, and nothing hurrying you along.

Verdict

The call

The clearest difference is in-app purchases: Sudora at none against Rytmos's 1. Sudora also leads on update cadence (every 3 weeks vs every 2 months). Rytmos's advantage is chart position (#143 vs unranked) and iOS requirement (11.0 vs 16). On price, ads and device support there is nothing between them.
