Outsmart the machine — grab the last coin to win.

1. 1 There are 21 gold coins on the table.
2. 2 You and the computer take turns. You go first.
3. 3 On each turn, drag 1, 2, or 3 coins into your chest.
4. 4 Whoever takes the very last coin wins!

💡 Tip: the secret is in how many coins you leave behind.
