How to play

Bigger Side practices judging which amount is larger. Two cards appear, each a number or a short sum like 3 × 7. Decide whether the left card is bigger, the right card is bigger, or they are equal. Each right answer earns points and fills a five-dot meter. A full meter raises your multiplier, and a miss empties it. Early cards are plain numbers, and later ones are written as sums. Press the left arrow, the down arrow or the right arrow, or use the buttons.
