The Goal
There are about fifty letter-atoms on the board each round. Tap them to spell words and submit before they decay. Three rounds, each about two minutes. There is no clock. The atoms are the timer.
⚛︎Tap atoms to build a word, then Submit. Tap a selected atom again to deselect it, or use the backspace button. Cancel a word in progress with the X button.
☢︎Atoms decay and vanish over time. Rare, high-value letters go first. Every atom that decays unused costs you a point.
⏱︎If a selected atom decays, your in-progress word is lost. So, submit before it’s too late.
✦The more rare a letter, the higher its point value, and longer words earn a bigger length multiplier.
⊘Each word can be used only once. No repeats, even across rounds.
