How this bank works
Tap an answer A to D. Correct turns green, wrong turns rust and the correct one is shown.
Use Show hint before you commit if you want a nudge. The explanation appears after you answer.
Each explanation says why the key is right and why the tempting wrong answer is wrong.
Filter by Standard or Challenge, jump to a sub-topic, or shuffle. Your progress is saved on this device.
When you finish a set, use Retry wrong to redo only the ones you missed.
