# SEN vs riddleWorld

The clearest difference is in-app purchases: riddleWorld at none against SEN's 1. SEN'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. SEN sells 1 one-off in-app purchase. riddleWorld asks for nothing beyond the download.
