Up or Down

A particle sits on one of twelve energy levels. The next level is drawn at random. You call whether it will land above or below where the marker is now, and you can see what each call returns before you make it.

Where the levels come from

Electrons around an atom can only sit at certain energies, a bit like rungs on a ladder with nothing in between. When one jumps up or drops down, it does so in whole steps. Up or Down uses twelve rungs and a fair draw, and that is where the physics stops.

Like every game on tofuquark, this is entertainment only. Coins are fictional: they cannot be bought, sold or exchanged for money, goods or anything else, and there are no in-app purchases. If you run out, reset to 1,000 coins for free.
