Digidrizzle

Digits drizzle from the sky, how many sums can you find before the time runs out?

Quick rules:

• Three rounds, 30 seconds each. Each round has its own target sum (two digits, 10–99). Targets never repeat in one game.
• Only numbers strictly less than the current target can fall (positive integers from 1 up to target minus 1).
• Select at least two numbers that add exactly to the target. Submit to score.
• Each tile shows a value and a rarity color: cyan ×1 (common), magenta ×2 (uncommon), yellow ×3 (rare).
• Score adds (face value × rarity multiplier) for every tile in a valid submit. Used tiles disappear; new rain keeps falling.
• Target sum stays green. Selected tiles are red until you submit or clear; if a selected tile reaches the bottom, it respawns from the top so your sum stays valid.
