Predicate Cascade
Evaluate the rule. Tap the card. Faster.
How to play Predicate Cascade
A glyph appears above four condition cards. Tap the card the glyph satisfies — or press 1–4 on a keyboard.
Rules grow more complex as you advance, stacking properties you have to check before committing.
What it trains: rapid rule evaluation
Predicate Cascade drills the Boolean truth judgment behind formal logic: given a glyph and four candidate conditions, decide which condition the glyph actually satisfies — quickly and repeatedly.
As rules compound, the game shifts from perception to genuine evaluation: you're parsing conditions under time pressure, which is exactly where sloppy reasoning shows up.
Does brain training work? →Scoring & progression
Runs are short and scored — your best run sets your personal record. Strong runs feed your belt progression in the logic discipline — from white belt toward black — and your place on the global leaderboard.
