~~~ Note: Five Square is a Pay What You Want app. Download it for free and we’ll ask you to pay an amount that feels good after you’ve won a few games. You can also decide not to pay, or pay right away in the app's settings. ~~~ Ever gotten bored with regular solitaire, and all the luck involved in winning? Five Square is different. All the cards are visible at the start of the game, most layouts are winnable, and whether you win is determined almost entirely by how well you strategize and plan. That’s why we call it the Chess of Solitaire. And yet, unlike Chess, the rules can be described in little more than a sentence: ◆ Deal a 5x5 square of cards face up. ◆ Stack cards (or stacks of cards)… ◆ …onto others of the same suit or rank… ◆ …within the same row or column. ◆ Win by getting them all into one stack. That's it! People who enjoy Sudoku puzzles, Chess puzzles, or FreeCell will love Five Square. It's a thinker’s card game. Features: ‣ Four difficulty levels (2 Suit, 3 Suit, 4 Suit, and Challenge mode) ‣ Satisfying, beautiful cards that are a joy to use ‣ Concise How to Play guide with tips on best strategies ‣ Other ways to play (adding Jokers as wildcards or removing Face Cards to make the game easier) ‣ Gameplay statistics (Total Layouts Dealt, Wins, and a “Chess Wins” statistic for games won without restarting the layout or undoing multiple moves in a row) ‣ Customizable app behavior (turn on and off in-game sounds, haptic feedback, and more) ‣ Universal support for iPhone, iPod Touch, and iPad Can you get all the cards into one stack?

ONO's advantage is update cadence (every 2 months vs every 29 months). On price, rating, review sentiment and ratings volume there is nothing between them.
