Every daily Pour since launch. Each day serves the same five glasses to everyone, from an easy warm-up to two tricky shapes. Pick any day to play it. Archive rounds don't count toward your streak.
Each glass comes with an order like "Fill to 54%". Hold to pour and let go to stop. The flow speeds up the longer you hold, and you can top up but never pour water out.
The target is measured by volume, not height, and the glass has no markings. You have to read the shape.
A perfect pour is worth 100 points. Every 1% you're off costs 5 points, so 2% off scores 90, 10% off scores 50 and 20% off scores 0. Five glasses make a best possible day of 500.
Green means within 2%, yellow within 6%, red further off.
Our eyes judge height, but volume lives in the width. In a cone standing on its point, half the water sits 71% of the way up, because the wide top holds so much more than the narrow bottom.
Flip it into a pyramid and the halfway mark drops to under a third of the height.
