Casellina makes the most of large screens: on iPhone Duo, the board and its controls sit side by side, or on either side of the fold when it is half open, and the large grids are offered whenever there is room. On iPhone, every game can now be played in landscape too. In Mazzetto, the deal number keyboard can be dismissed with one tap.

Ponticello and Addendo now wear the colours of their icons: a midnight-blue board, cream islands and squares, terracotta bridges and clues.

With the largest text sizes, the home screen, the solitaire games and the Studiolo show one tile per row, so every game's name stays readable in full.

Casellina grows! Mazzetto brings five solitaire games: Klondike, Spider, FreeCell, Pyramid and TriPeaks, each with its daily challenge. The Studiolo opens with Pennellino, a brand-new puzzle of brushes and colours. And in every game, the hint now shows the square to play right away, and why.

Pareggio is now Casellina! Your takuzu is still here, with your games, your statistics and your Pro purchase, which now unlocks every game. And eight new puzzles are waiting: sudoku and Mini, stars, kakuro, hashi, shikaku, a numbered path, crossword sums and mine-clearing without guessing. A daily challenge for each.

• Statistics: challenges solved, games by size and level, days played, with no streak to keep up; with Pro, your times and mastered techniques • Techniques guide: every technique explained, with an example from a real grid • The purchase button now says everything Pareggio Pro adds

• Choose your pieces: circles, squares, diamonds, stars or 1 and 0, in five colour sets (extra shapes and colours with Pareggio Pro) • Clearer hints, in three steps: where to look, why, the answer • "Another hint" offers a different deduction elsewhere in the grid • 80,000 grids, and a daily challenge that is always new • The Start button is always visible • Pareggio now speaks Chinese, Korean, Arabic and Russian
