"That steak looks like half a pound." "Those two lines are definitely the same length!" Everyone says "looks about right", but is it really?
By Eye is a visual intuition puzzle game. No formulas, no calculations: take a glance, dial in your estimate and watch the reveal. Will it be a pinpoint triumph or a hilarious reality check?
Numbers are regenerated on every retry, so there is nothing to memorize.
Highlights
- Six kinds of puzzles: proportions, quantities, moving objects, hands-on tasks, optical illusions, physics and geometry.
- Day vs. night: take your time by day; at night the puzzle flashes once, then goes dark.
- The reveal: 0.2% off or 28% off, you see it instantly.
- Endless mode: unlocked after the day levels, with leaderboards.
