# First Planet Puzzle vs Encyclopedia

The clearest difference is iOS requirement: First Planet Puzzle at 9.2 against Encyclopedia's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. First Planet Puzzle sells 1 one-off in-app purchase and Encyclopedia sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
