Rewards

Training Rewards

Each value shows the units earned for one correct column, example, or answer. Wrong answers earn no units. The same rules apply to every Tables and Speed Run mode.

Units from correct answers add up during training. At the end of a solo session, positive units are sent to your account; the result page confirms whether they were saved. In multiplayer, units appear in the results but are not added to your account.
