# Sudoku vs Flake Demo

The clearest difference is in-app purchases: Flake Demo at none against Sudoku's 7. Flake Demo also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 3 months). Sudoku's advantage is iOS requirement (12.0 vs 15.6). On price, review sentiment and device support there is nothing between them.

Both are free to download. Sudoku sells 7 one-off in-app purchases. Flake Demo asks for nothing beyond the download.

Sudoku ships an update every 3 months, Flake Demo every 5 weeks. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
