Klondike solitaire, rebuilt – the game is the one you know, everything around it is new. BUILT FOR ONE HAND Solitaire was designed for a table, and most apps still deal it that way – seven columns crushed across the width of a phone. OK Solitaire runs vertically up the screen instead, so every pile sits in comfortable reach of your thumb. Set it up for the left hand or the right. Switch to the squished horizontal version if you really want. PICK UP A RUN, OR PART OF ONE Touch a card and you lift the whole run beneath it. Keep holding and you can dive into the stack, scrubbing down to take a shorter run instead – no pinpoint tapping at a half-covered corner. Double-tap anything that can go home, and it goes. IT KEEPS UP WITH YOU Undo runs all the way back to the deal. Auto-flip turns the cards you were only going to turn yourself. Once a hand is mathematically decided, a FINISH button appears and plays it out, so you never sit clicking through a foregone conclusion. Every action has its own haptic – the lift, the drop, the draw, the win. NOTHING IN THE WAY No ads. No account. No pop-ups between hands, no currencies, nothing nagging you. Three themes, including a true black for OLED, and a board that fills the screen. THREE WAYS TO PLAY Standard Play – Klondike as it comes. One-card or three-card draw, wins and losses alike. Daily Challenge – one deal a day, the same one for everyone, and always winnable. Finish it and your time goes on the leaderboard. Only Wins – every deal winnable before you see it, for when you want the game without the dead ends. INSIGHT Stuck, and not sure whether it is you or the deal? With INSIGHT mode, you'll know whether the deal was ever winnable, whether it still is, and – if you have played into a dead end – how far back to rewind to the last position that still had a win in it. Game Center leaderboards for best time, games won, and the daily. Plays entirely offline. SUBSCRIPTION The extras – the Colorful and Dark themes, and INSIGHT mode – are available as a yearly auto-renewing subscription or as a one-time purchase. The subscription renews automatically unless cancelled at least 24 hours before the current period ends, and can be managed or cancelled in your Apple Account settings.

Verdict
The clearest difference is price: OK Solitaire at Free against KLAC's $1.99. OK Solitaire also leads on rating (5.0 vs 4.5) and update cadence (daily vs every 10 days). KLAC's advantage is ratings volume (141 vs 6) and chart position (#101 vs unranked). On ads, in-app purchases and monetization model there is nothing between them.
