Casellina means “little square”: every one of these games is played one square at a time. Each keeps its own solver, levels and techniques guide; they share one home screen, one daily challenge each, and one purchase.

Plays anywhere, offline

Every grid, every daily challenge and every hint is made or stored on your device. On a plane, abroad without data, in the metro or at the cottage: everything works, with no connection and no roaming. Even the daily challenge comes from the date, not from a server.

A daily challenge for every game

Worked out from the date on your device, with no server involved: gentle on Monday, tough on Sunday. The home screen shows each game’s challenge and how many you have solved today.

Honest levels

Every grid has exactly one solution. Its level is the hardest technique it truly needs, and the app names it. The solvers never guess, so neither do you.

Hints that teach

Where to look, then why, then the move. Each game comes with a guide to its techniques, shown on real grids.

Free, and what Pro adds

Every game in full, every level and every hint, and every daily challenge, free for good. The free version limits the number of free games each day, across all the games together. Casellina Pro removes that limit in every game, now and to come, paid once and shared with your family.

Pareggio players keep everything

Casellina arrives as the 2.0 update of Pareggio: your games, statistics and Pareggio Pro purchase carry over, and that purchase now unlocks every game. Stelletta’s games are picked up on the same device, too.

It asks for no permissions at all

Your games stay on the device and, if you leave iCloud on, in your own private iCloud, which we cannot open. There is no server of ours and no analytics. The privacy page says the rest.

Thirteen languages: English, French, German, Spanish (Spain and Latin America), Italian, Japanese, Korean, Portuguese (Brazil and Portugal), Russian, Arabic and Chinese (Simplified). iPhone in portrait; iPad in all four orientations.

Casellina is on its way to the App Store, as the 2.0 update of Pareggio. This page will carry the link when it is there.
