# NAND vs Masyu

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

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