Mahjong Haven
Read full descriptionHide full description
Match the pairs. Clear the board. Unwind. Mahjong Haven is classic mahjong solitaire, the single-player tile-matching puzzle. Tap two free tiles that show the same face to remove them, and keep going until the whole board is clear. Easy to learn in seconds, deeply satisfying to master. TWO WAYS TO PLAY - Levels: 30 hand-crafted layouts, from gentle 24-tile starters up to the 144-tile classic turtle - Daily Challenge: the same board for every player each day, with a streak to build and keep WHY YOU WILL STAY - Every board is dealt so a solution exists, and a shuffle re-deals the rest into another solvable arrangement, so you are never truly stuck - Unlimited undo, always free, so a wrong tap never costs you the board - A high-contrast toggle swaps every tile face for a bolder set, and the smaller starter boards render with extra-large tiles - Ten hand-tuned table themes to unlock as you play, all free - Fully offline: play on a plane, on the subway, anywhere with no wifi - Smooth animations, gentle haptics, and satisfying match sounds MADE TO BE FAIR No pay-to-win. In Levels and Daily Challenge your first hint each board is free, and you can watch a short video for another. Stuck with no pair left? Watch a short video to reshuffle the remaining tiles, or just undo instead. Undo never needs a video and never runs out, so a stuck board is never a dead end. ONE PURCHASE, NO MORE ADS Mahjong Haven is free to play, supported by ads between boards. A single Remove Ads purchase turns them off for good. No subscriptions. Play in 33 languages.

Verdict
The clearest difference is ads: SUM at none against Mahjong Haven's shown. SUM also leads on update cadence (every 3 days vs every 5 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.
