Two Mathematical Variants. Infinite Strategy.

Invented by legendary topologists, the game plays out on a planar surface where space is your only limit.

Classic Sprouts

Start with a set of dots. Draw curves connecting one dot to another, or to itself. Placing a new dot in the middle of each curve. Since no dot can exceed 3 connections, the degree limits create intense boundary traps where you must isolate the opponent.

Degree Limit: 3 connectionsLength: 2N to 3N-1 moves

Brussels Sprouts

Played with crosses (+) instead of dots. You connect open arms of crosses and place a perpendicular line segment across the curve to form a new cross with two new open arms. Conway's Theorem proves the game length is always predetermined at 5n-2 moves!

Euler characteristic logicLength: Exactly 5N-2 moves

Designed with Sensual Aesthetics

Switch seamlessly between two premium custom themes that highlight different topological atmospheres.

Theme A

Classic Notebook

Vintage cream sketch paper with blue grid lines, graphite-colored ballpoint curve drawings, and faint pencil-scratch effects. Reminiscent of a Cambridge lecture hall notebook.

Dead nodes ringed with light gray halos

Inspired by Conway's original hand sketches in 1967.

VS

Theme B

Siber-Glow Mode

Electric cyber-neon aesthetics. Features glowing cyan and pink curves connecting node particles on a glassmorphic background grid, pulsing with tactile haptic vibrations.

Dead node particles implode in cyan light

Ideal for playing in dark ambient environments.
