Two things appear. Tap whichever is bigger on the measure named at the top. Right answer keeps the chain going — forever. One wrong tap ends the run.
1
Read the measure. Heat, age, size, speed — it changes every round.
2
Watch the wording. Some rounds flip to "which is lower?" Misread and you're out.
3
It gets harder. The longer your chain, the closer the two values become.
4
Earn ranks. Every level unlocks a new rank and avatar — kept for good.
