Make 24 DUEL

Two players, one phone. Lay it flat between you. You both get the same four numbers: first to make 24 wins the round.

• Tap a number, an operator (+ − × ÷), then another number. They merge into one.
• Keep going until one card is left. If it's 24, you win the round.
• Undo takes back a step, Reset starts over. If you're both Stuck, the answer is shown.
