HIDDEN NUMBER MEMORY · 10 ROUNDS
Memorize scattered numbers. After you choose 1, every remaining label disappears.
Play up to 10 increasingly difficult rounds with three lives. Losing all lives ends the test.
READY?
The field changes every round. Keyboard players can Tab through spatial positions.
NUMBER FIELD READY
Touch or mouse: select positions directly · Keyboard: Tab / Shift+Tab, then Enter or Space. Remember the positions before choosing 1.
HOW TO PLAY
Scan the scattered tiles and memorize where each number appears.
Choose 1. Every remaining number is immediately covered, but each tile stays in place.
Continue with 2, 3, and upward before each current-selection timer empties.
SPATIAL ORDER MEMORY
The first choice switches the task from visible ordering to spatial recall. You must remember both each number and its location while moving upward through the sequence.
Standard mode uses ten progressively larger sets. Three misses end the run, and any unplayed rounds are recorded as forfeited so results remain comparable.
