21 Solitaire
About
21 Solitaire is a card puzzle game inspired by the blackjack goal of reaching 21. It blends the relaxed pacing of solitaire with the mental arithmetic of card games, making it a satisfying daily brain workout that exercises both mathematical thinking and forward planning.
How to Play
Tap a column to place the active card there. Fill a column so its cards total exactly 21 to clear it and earn points — go over 21 and you lose that column. Aces count as either 1 or 11. If you're stuck, tap the deck to swap to a different card. You can do this up to 3 times, so use it wisely.

Tips
- Save your deck swaps for when you're truly stuck — you only get 3, and running out at a critical moment can end your game early.
- Use Aces flexibly — placing an Ace when a column is at 10 lets it act as 11 to hit exactly 21.
- Try to keep multiple columns active at once so you always have somewhere useful to place any card.
