A sequence of blocks flashes; repeat it by tapping them in order, except the blocks slide around after lighting and fake blocks blink to throw you off.
Each round a path of blocks lights up one by one. Once the flash ends you tap them back in the same order, but the blocks drift in real time, turning your memorised path into a hunt for moving targets. Clear a round and the span grows by one. Decoy blocks blink during recall; tapping one, or any block out of order, costs a life.
Corsi Climb is a memory game inspired by the classic block-tapping span test, building visuospatial memory.
Tapping back a sequence of blocks that lit up one by one is the Corsi block-tapping test, a standard assessment of visuo-spatial short-term memory. The sequence grows until performance breaks down, and that length is the Corsi span — typically about five or six.
The original twist is that the blocks drift in real time, so the remembered path becomes a hunt for moving targets.
That separates two things the clinical test deliberately conflates. Corsi measures memory for a spatial sequence; if the blocks move, remembering where is no longer enough, and you must have encoded the order as a sequence of objects rather than of positions.
Corsi Climb is an original free browser memory game inspired by the classic block-tapping span test, with drifting targets and decoys for an extra twist. Built in-house for PlayPendium.
