SPATIAL MEMORY · 10 ROUNDS
Watch the nine blocks light up, then reproduce the same spatial sequence.
Play ten rounds from span 3 to span 12. Wrong answers count, then the next span continues.
READY?
Block positions stay fixed. The path changes every round.
Mouse or touch: select blocks · Keyboard: Tab to a block and press Enter or Space.
HOW TO PLAY
Watch the blocks flash one at a time across the irregular board.
Wait until the demonstration finishes and the answer timer begins.
Select the same block positions in exactly the same order.
SPATIAL SEQUENCE
The blocks have no visible numbers during play. You remember a route through space rather than a verbal list.
Longer spans may revisit a block, but the same block never flashes twice in immediate succession.
ENTERTAINMENT ONLY
Standard mode continues after mistakes so every run contains ten comparable rounds.
