No account and no data collection Number Drop is a falling number-merge puzzle: drop, stack and double. Over flashy effects, it values the fun of thinking one move at a time and the satisfying "pop" of a merge. HOW TO PLAY • Drop the next number into any of five columns • When it touches the same number above, below or beside it, they merge and double • Touch two matches at once and it jumps ×4 • If the new number matches a neighbor, it merges again — that's a chain • When the stack reaches the ceiling and nothing fits, your run ends FEATURES • Daily Challenge — numbers set by the date, one 3-minute score attack per day • Classic — play until the stack tops out; quit anytime and continue later • Endless — no ending and no score, just dropping and stacking • Guided practice — six moves with a guide explaining how to think about each one • Preview of the next two numbers, plus a dotted landing guide on your column • Number themes in traditional Japanese colors: Indigo, Crimson, Bamboo, Ink and Colorful.
