Small, hand-built mobile puzzle games.

Knock

A quiet puzzle about consequences. Flick a piece, it hits the next, the chain does the rest. The game plays offline and asks an age question on first launch. Players under 13 use protected mode without ads, sign-in, public rankings or real-money purchases. Players 13–17 can use the online features and shop, but see no ads. Ads are available only for adults. For players 13 and older, its daily and all-time leaderboards use the network: the app creates an anonymous player profile for you (a random number and a random public name, no email and no password), and you can delete it from Settings → About & Legal → Privacy & Data at any time. The game shows ads from Google AdMob and offers optional in-app purchases. Signing in with Google or Apple is optional and saves your progress to an account; you can delete that account and its cloud save from the same Privacy & Data screen (how). The privacy policy says exactly what is collected and how long it is kept.
