One path hits the target.

A small grid of nodes, left to right. You start on a given number, and every connection between columns carries an operation — +5, −3, ×2. Walk the maze by choosing one edge at each step; the operations apply in sequence to your running value.

start: 7                     target: 24
  ○ ──+5──▶ ○ ──×2──▶ ○      7+5=12, 12×2=24 ✓
   ╲─−3──▶ ○ ──+9──▶ ○      7−3=4,  4+9=13  ✗

Exactly one path through the maze produces the target — every other route lands on the wrong number.

Tap the edges to build your path from the start column to the last one, then submit. Right path: you score and a new maze appears. Wrong: it counts as a miss — re-trace and try again.

Early mazes are short and use only + and −. Later ones grow to six columns, three rows, and add multiplication — which changes everything, because a ×2 late in the path doubles all your earlier choices.

You and your opponent solve the same mazes on a 90-second clock. Most mazes completed wins; ties break on accuracy, then speed.
