Play Brain Bolt online
Brain Bolt is a 12-round brain-teaser gauntlet: a new micro-puzzle every few seconds, from odd-one-out and number sequences to a Stroop color trap and a green-light reaction test.
Each round gives you 6.5 seconds. Answer right to advance; a wrong tap or timeout costs a strike. Three strikes and the run is over.
Clear all 12 rounds to win. Every puzzle is generated fresh each run, so no two gauntlets play the same.
Your best run (rounds cleared, 0-12) is saved in your browser.

Tips for a better run
Read the round title first — it tells you exactly what to do before the timer pressure builds.
On ASCENDING, scan all six numbers before tapping; the smallest is rarely top-left.
On STROOP, ignore what the word says — lock onto the ink color.
On TAP COUNT, count out loud; one extra tap fails the round.
On FLASH RECALL, stare at the star's position, not the shape.
