About Aced 21: Card Number Puzzle
Aced 21 is a puzzle about one number.
Press a card and drag through its neighbours. When the hand you have traced adds
up to exactly 21, it clears. Face cards count ten. An Ace counts one or eleven —
whichever the hand needs. That is the whole rule.
This is a puzzle, not a casino. There is no betting, no wagering and no dealer.
Nothing is left to chance: every board can be reasoned out, and every level is
verified beatable before it ships. (If you know the classic game of 21, you will
recognise the arithmetic and nothing else.)
WAYS TO PLAY
🃏 Levels
Hand-built puzzles gathered into named chapters, each with its own objective.
New ideas arrive one chapter at a time, so you learn one thing at a time.
∞ Free Table
No objectives, no move limit. Keep making hands until the table runs dry, then
try to beat your own best.
📅 Daily Table
One board a day, the same for everyone. Solve it and keep your streak.
WHAT MAKES A HAND SING
• The flexible Ace — one or eleven, whichever gets you to 21
• Blackjack: an Ace and a ten-card, in two
• Flush: one suit all the way through, for double
• Jokers that stand in for any card, and Splits that break a tile in two
MADE TO BE CALM
No timers. No lives. Nothing expires while you sit and think.
• Hints and undos when a table defeats you — never required
• Watch an ad for chips if you want to, never because you must
• Separate sound and haptics switches
PLAYS ANYWHERE
Works fully offline. No account needed — your progress saves on your device.
