Neutron is a board game released in 1978 for 2 players, 10–15 minutes per game, and ages 8 and up. It was designed by Robert A. Kraus (II) and its main mechanics are Square Grid and Grid Movement.
Neutron is a two-player abstract strategy board game played on a square board with a 5x5 grid. Each player has five tokens of different colors that start on the baseline of the board closest to them. A single token of a third color called the Neutron starts in the center of the board. To win, either surround the Neutron or move it to your baseline. On a turn, a player does these two actions in this order: Move the Neutron: Move it any direction to the furthest vacant square possible without leaping over other tokens; if you can't move it, you lose (because the other player has surrounded it). Move one of your tokens: Move it any direction to the furthest square possible without leaping over other tokens. On the first turn, the starting player skips the Neutron move. Neutron was invented by Robert A. Kraus and first appeared in 1978. Bobail is nearly identical to Neutron, except in Bobail the Neutron can only move one vacant adjacent space. The publishers of Bobail claim that it's a traditional African game that pre-dates Neutron, but there is no evidence to back up this claim.
Neutron 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 Neutron is 10–15 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 Neutron for ages 8 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.
Neutron has a complexity rating of 2.1 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.
