Spline+

Spline+ is an extension of Spline with ball movement.

• Start: The board starts empty.
• Play: Players take turns either:
  1. placing a ball of their colour on any playable point, or
  2. moving a ball of their colour to any playable point. The ball cannot be placed on any ball that the move caused to drop.
• End: A player wins by making a flat line of their colour spanning side to side, or corner to corner, on any level. If multiple spanning lines occur (due to a drop) then the longest line wins, otherwise the mover wins.

The following example shows a losing move for Black. If the black ball shown is removed, then the two balls above it drop down to create a black line of size 3 but a white line of size 4.

Ball movement adds depth to the basic Spline idea by making games longer and allowing tricky multi-level moves.

Balls are forbidden to stack on self-drops to avoid cycles.
