School gameplay
School is the onboarding world. It teaches every chess piece through level design alone, not text. Kindergarten gives you a single rook on a 3x3 board with one target. By 12th Grade you are juggling a queen and a knight on a full 8x8. The Final Exam hands you all six piece types and asks you to light 12 targets in a graduate silhouette pattern.
School is where you learn the game. Each grade introduces a new chess piece, starting with the rook in Kindergarten and ending with the pawn in 11th grade. The levels are designed so you discover each piece's attack pattern by placing it, not by reading instructions. If you drop a piece on the wrong square, it bounces back and you try again. No penalty, no timer, no lecture.
All six pieces, introduced one at a time across 12 grades
Kindergarten through 3rd grade use small boards (3x3 to 5x5) with a single piece. 4th grade jumps to 8x8 with the queen. By 12th grade you are placing two pieces. The Final Exam is an 8x8 with all six piece types and 12 targets.
