# Sudoku Shapes vs Color Sequence Memory

The clearest difference is in-app purchases: Color Sequence Memory at none against Sudoku Shapes's 1. Color Sequence Memory also leads on ads (none vs shown). Sudoku Shapes's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.

Both are free to download. Sudoku Shapes sells 1 one-off in-app purchase. Color Sequence Memory asks for nothing beyond the download.
