How to play

  1. Select three cards. Select one again to remove it.
  2. Add their values and check their suits. All three suits must be different.
  3. Press Check trio. Find every distinct valid combination; cards stay on the board and may be reused.

A worked example

4♣ + 7♦ + 10♥ = 21, with three different suits: a valid trio. 4♣ + 7♣ + 10♥ is not valid because two cards share a suit. J♠ + 2♦ + 8♥ = 21 is valid: a Jack is 11 in this puzzle.

A small daily habit

Daily boards have three to six trios and change at midnight UTC. Progress, hints and misses are saved for the latest 30 daily boards in this browser. A fresh board is unlimited practice and is not saved. Hints select one unfound trio but do not award it automatically.

Hints and misses are recorded, not penalized with a timer. Clearing browser storage removes progress. The daily puzzle is deterministic; it is for fun, not a secure contest.
