Spline+ is a board game released in 2011 for 2 players, 15 minutes per game, and ages 7 and up. It was designed by Néstor Romeral Andrés and its main mechanics are Square Grid, Physical Removal, and Layering.
Spline+ was evolved from Spline by adding ball movement. It's a ball-stacking game that can be played with a Series: Shibumi set, as it uses a 4x4 holes board and balls in two colours (white and black). Larger boards can also be used, but no more than 6x6 is recommended. Rules: Definition: A pinned ball is a ball that supports 2 or more balls on the level above. Pinned balls cannot be moved/removed. Movable balls are balls that are not pinned. 2 players. The board starts empty. Starting with white, players take turns either: a) placing a ball of their colour on an empty space or platform (2×2 arrangement of marbles) or... b) moving a movable ball of their colour already on the board to another valid location. If supported balls drop as a consequence of the ball removal, you can't place your ball on top of the dropped balls. Aim: The first player making a full line of his color on any layer wins. Lines may be diagonal. This is, for a 4×4 set, a 4-in-a-row on the first layer, or a 3-in-a-row on the 2nd layer, or a 2-in-a-row on the 3rd layer. In case of several lines being created as a result of balls dropping, the largest line prevails.

Spline+ supports 2 players according to the catalogue. This is the publisher’s listed player count, so the game is designed for exactly that number of participants. Variants for other group sizes, if any, are described in the rulebook of your edition, so check it before setting up a different configuration.
The listed playing time for Spline+ is 15 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Spline+ for ages 7 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Spline+ has a complexity rating of 2.3 out of 5 from BoardGameGeek players, which makes it a medium-light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
