Play Qtris... Σ
Welcome to the Qtris game! It's like Tetris but with quantum states! To play:
You will see a series of digits in the lower box. As quickly as you can, press either the "E" key or the "O" key (or on mobile, the "Even" or "Odd" buttons) if you think most of the digits are Even, or Odd.

After choosing, a row of symbols will appear in an upper box:
X = Correct (1pt)
X = Correct (time bonus +1pt)
X = Incorrect (0 pts)
X = Timed out (0 pts)

Current High Score: 53 by RB
