Twindle is a daily arithmetic puzzle that challenges your number intuition.
Two rows of five numbers share the same four operators (+, −, ×, ÷). Find the one combination that makes BOTH rows equal the target.
HOW TO PLAY
Tap an operator chip at the bottom to fill the next empty slot. Once all four slots are filled, your answer is checked automatically. Use Undo to take back a move, or Reset to clear all slots.
The twist: both rows share the same operators in the same positions. One solution must satisfy two equations at once — that's the Twindle challenge.
EXAMPLE (target: 10)
Row 1: 6 _ 3 _ 7 _ 1
Row 2: 2 _ 9 _ 2 _ 6
Answer: × − −
6 × 3 − 7 − 1 = 10 ✓
2 × 9 − 2 − 6 = 10 ✓
