# Sudoku vs 数独训练营

The clearest difference is in-app purchases: 数独训练营 at none against Sudoku's 1. 数独训练营 also leads on update cadence (every 5 days vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Sudoku sells 1 one-off in-app purchase. 数独训练营 asks for nothing beyond the download.

Sudoku ships an update fortnightly, 数独训练营 every 5 days. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
