How to play
Math: Hit the number
Use the 6 numbers and the four operations to reach the target. You don’t have to use every number.
Physics: Estimate
Guess the value of a real quantity, like the speed of sound. Hints tell you whether to go higher or lower and how close you are.
Chemistry: Guess the element
Find the element from the periodic table in up to 6 guesses. Every miss reveals a new clue.
Biology: Connections
Sort 12 terms into 3 hidden groups of 4. Watch out for the tricky ones!
What the colors mean
- Correct
- Very close (or same period/group in chemistry)
- Close
- Far or wrong
For teachers
The challenge makes a great class warm-up: put the page on the projector and solve the rounds together. Practice mode creates extra challenges whenever you want.
