COMPARE FAST · 20 TRIALS
Choose the side with the larger number—or EQUAL when they match.
Complete exactly 20 comparisons. Wrong answers count and advance.
READY?
Use Left Arrow or A, Right Arrow or L, and Down Arrow or E for equal.
Keyboard: ← / A for left · ↓ / E for equal · → / L for right. Touch: tap a labeled button.
HOW TO PLAY
Start the game and read the two large integers.
Choose LEFT or RIGHT for the larger value. Choose EQUAL when both values match.
Complete all 20 standard trials, or keep a perfect streak against a shrinking timer in endless mode.
NUMBER COMPARISON GAME
Each trial combines visual scanning, number magnitude recognition, a three-way decision, and a quick response. Equal pairs appear alongside left-larger and right-larger pairs.
This is a recreational browser game, not a clinical or diagnostic assessment. Device latency, input method, attention, and practice can all affect the result.
READ YOUR RESULT
Standard accuracy is the percentage of all 20 answers that were correct. Average and best reaction times use correct answers only.
For a useful personal comparison, repeat the same mode on the same device and with the same input method.
QUESTIONS

Every correct answer adds to your streak and starts another comparison with a shorter deadline. One wrong answer or timeout ends the run.
Yes. The three large buttons work with touch, mouse, and assistive input. Desktop players can also use arrow keys or A, L, and E.
