Scratch-off lottery probability game
Against a clock, or not?
Same ticket, same questions, same payout. The clock is the only difference - and it is the one that makes the answers feel different.
Untimed is where you learn the method. Timed is where you find out whether you actually know it - a screen never gives you the second one.
