HOW IT PLAYS

PICK A MISSION

Add, subtract, multiply, divide, squares, cubes or primes, at Cadet, Pilot or Ace. Mix draws from the player's grade.

SHOOT THE MATCH

Every wave has a target. Tap the attackers that equal it. A wrong shot or an escaped match costs a shield. Five waves, then a boss.

LEARN FROM MISSES

Each miss becomes a REMEMBER card. Weak facts turn into short drills, and a fact goes solid after three clean hits.

CLIMB THE RANKS

Stars, badges, XP and a path through the grade's curriculum. Unlock bodies, visors and hats in the Dino Lab.
