📐 Rounding & Estimation Number Snake Arcade

Master rounding to the nearest 10, 100, and 1,000! Slither across the retro grid and eat the correct rounded benchmark number.

🎯

Look at the target equation at the top of the arena (e.g. 7 × 8 = ?).

🐍

Navigate your snake using arrow keys, WASD, swipes, or the touch D-Pad to eat the correct number orb.

⭐

Eating correct answers grows your snake, levels up your speed, and triggers combo point multipliers.

The 5 Benchmark Rule: If the deciding digit to the right is 5, 6, 7, 8, or 9, round up to the next higher landmark (e.g. 68 rounds up to 70).
Four or Less Stays at Rest: If the deciding digit is 0, 1, 2, 3, or 4, round down to the current landmark (e.g. 63 rounds down to 60).
Identify Bounding Landmarks: For nearest 100, place the number between two bounding hundreds (348 is between 300 and 400). Since 48 is below 50, round to 300.
Spot Landmark Numbers on the Grid: Rounded answers always end in 0, 00, or 000. Look for trailing zero orbs across the snake arena for fast visual identification!
