# Trace The Line vs Sudoku

The clearest difference is iOS requirement: Trace The Line at 15.0 against Sudoku's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Trace The Line sells 2 one-off in-app purchases and Sudoku sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Trace The Line ships an update every 4 weeks, Sudoku fortnightly. The most recent releases landed on October 31, 2026 and November 10, 2026 respectively.
