Casellina, fifteen logic and card games in one app, arrives on the App Store
Studio Nidello brings its nine grid puzzles, five classic solitaire games and Pennellino, an original puzzle, together in one iPhone and iPad app. All playable offline, each with a daily challenge, with no ads and no account.
Canada, 30 October 2026. Studio Nidello announces Casellina for iPhone and iPad: fifteen logic and card games in one app, all playable offline. Casellina means "little square" in Italian: every one of these games is played one square at a time.
What Casellina brings together
- Nine grid puzzles, each with its own solver, levels and techniques guide: Quadretto (sudoku, plus a 6×6 Mini), takuzu, Stelletta (stars on irregular regions), Addendo (kakuro), Ponticello (hashi), Toppetta (shikaku), Filino (a numbered path), Incastro (crossword sums) and Bandierina (mine-clearing without guessing).
- Mazzetto, five solitaire games with their classic rules: Klondike, Spider, FreeCell, Pyramid and TriPeaks. Players can choose to receive only deals known to be winnable. The cards are drawn by the studio.
- The Studiolo, Nidello's own puzzles, opening with Pennellino: three brushes whose colours mix where they cross.
What sets them apart
- A daily challenge in every game, the same for everyone, worked out from the device's date with no server: gentle on Monday, tough on Sunday.
- Honest levels. Every grid has exactly one solution, and its level is the hardest technique it truly needs. The solvers never guess, so the player never has to.
- Hints that explain. A hint shows the square to play and why; every grid puzzle has its techniques guide, shown on real grids.
- Anywhere, offline. Grids, challenges and hints are made on the device: on a plane, abroad or at the cottage, everything works with no connection.
Privacy
Casellina has no account, no ads and no usage analytics, and the studio runs no server for it. Games stay on the device and, if the player keeps iCloud on, in their own private iCloud.
Availability
Casellina is free on the App Store for iPhone and iPad, in 13 languages and worldwide. The free version includes every game in full, every level, every hint and every daily challenge, plus three free games a day across all games. Casellina Pro costs CA$7.99 once, with Family Sharing: unlimited games in every game, present and future, detailed statistics and every colour.
