It's nice but the games are the same after solving them, so it's not as engaging once it's mastered. There's no real reason to keep playing the same games. The ad persists after purchase and there is always the impulse/urge/suggestion to keep downloading and purchasing. It asks for a parent's permission and it can mean having to say no unless you download everything despite being "budget friendly".

Would be nice if the free games were not displayed on the same page as the games that are locked and need to be purchased. Kid keeps clicking on them and can't enjoy the app properly. And the free games are in an obscure location on the page (upper right side, next to back button) while the overwhelming majority of games that are locked fill the screen. Younger kids will almost always back of the game they're playing and end up on that screen, clicking everything, unable to play anything.

I wish all of them to be free like with adds it's fun but money makes it not and it's a short game not worth the money
