Find the numbers 1 through 150 in ascending order. Tap 1, then 2, then 3 — all the way to 150. No hints, no shortcuts.
Numbers are spread across 3 floors. Use ▲ ▼ to move between them.
Choose how found numbers are marked — fill, highlight, pencil, eraser, reveal one at a time, or none — from the side panel. None is the closest match to the printed book.
Tap the pause icon next to the clock to stop anytime. The game also pauses itself if you switch tabs, close the page, or step away — pick up right where you left off.
One new puzzle drops every day.
