Trace words across a letter grid, watch the tiles fall away, and snuff the rising fire before it reaches the top.
Drag across touching letters to spell a valid word. The word's tiles disappear and the columns collapse under gravity. Each attempt you commit, valid or not, pushes a burning tile one row higher. Consume that tile or drain the whole board before the fire reaches the top to clear the round.
Spell Cascade builds spelling and vocabulary by having you trace real words out of a collapsing letter grid, so recognising and recalling spellings is the core of the play.
Tracing a word through touching letters is Boggle's adjacency, introduced in 1973.
The original pressure is that every attempt costs — valid or not, a committed guess pushes a burning tile one row closer.
Charging for failures changes what a word hunt rewards. Boggle costs nothing to guess wrongly, so the optimal strategy is to try everything plausible; here a speculative word is a real expense, which makes certainty worth something and turns spelling into a decision rather than a sweep.
