# Collaborative Sudoku vs Drift

The clearest difference is update cadence: Drift at every 8 days against Collaborative Sudoku's every 3 weeks. Collaborative Sudoku's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Collaborative Sudoku ships an update every 3 weeks, Drift every 8 days. Both last shipped on October 31, 2026.
