Solo 33
Read full descriptionHide full description
Solo 33 is peg solitaire the way it was meant to be played: a wooden board, 33 holes, 32 marbles and one empty space in the middle. Jump a marble over its neighbor, take the jumped marble off the board, and keep going. Leave a single marble in the center and you have solved it. Simple to learn. Genuinely hard to master. HOW TO PLAY • Select a marble, or drag it straight to where you want it • Jump horizontally or vertically over an adjacent marble into an empty hole • The marble you jumped over is removed • The game ends when no jump is left — aim for one marble in the center FEATURES • The classic 33-hole English board • Click, tap or drag — whichever feels natural • Unlimited undo and redo, so one bad jump never ends a good run • Built-in solver: when you are stuck, Hint shows a move that still leads to a perfect finish • Your game saves itself — close the app mid-puzzle and pick it up later • Statistics for games finished, perfect solves, best result and total moves • Sound and haptic feedback, each switched on or off on its own • Full VoiceOver support • Native on iPhone, iPad and Mac NO NONSENSE • No ads • No subscriptions • No account, no sign-up • No internet connection needed • No data collected about you Solo 33 is a quiet game. Nothing is counting down, there are no lives to lose and no streak to protect. Play a board over a coffee, or spend a week chasing your first perfect solve.
