Whack-a-Mole

Whack-a-Mole trains sustained reactive attention with the classic grid paradigm.

Moles pop up in random grid cells and disappear quickly. You must spot and tap each before it hides.

Empty-cell taps incur a misclick penalty, so you cannot just spam-tap the grid. Precision matters.

The fixed grid layout differs from free-position games — it trains efficient grid scanning rather than wide attentional sweep.

Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.

Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.

1. Moles pop up briefly in random grid cells.
2. Tap each mole before it hides.
3. Tapping empty holes counts as a misclick.
4. Use peripheral vision — fixate the grid center.
