# Sudoku vs Stackbound

The clearest difference is in-app purchases: Sudoku at none against Stackbound's 1. Sudoku also leads on ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.

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