# Lotto Engine 2D vs 행운 숫자

The clearest difference is in-app purchases: 행운 숫자 at none against Lotto Engine 2D's 1. Lotto Engine 2D's advantage is ads (none vs shown) and device support (3 vs 1). On price there is nothing between them.

Both are free to download. Lotto Engine 2D sells 1 one-off in-app purchase. 행운 숫자 asks for nothing beyond the download.
