Subatomic: An Atom Building Game is a board game released in 2018 for 2–4 players, 40–60 minutes per game, and ages 10 and up. It was designed by John Coveyou and its main mechanics are Hand Management, Deck, Bag, and Pool Building, and Action Points.
Subatomic: An Atom Building Game is a deck-building game in which players compete to build a number of available elements, which score them points. Each player starts with the same small deck of cards that consist of proton, neutron, and electron cards. They use these cards to build upon their current atom (by playing these cards face-up as subatomic particles) in an attempt to construct one of the available element cards. Alternatively, players may use their hand of cards to purchase more powerful cards for later use (by playing them in combinations of face-down cards as energy and face-up cards as subatomic particles). Subatomic introduces a unique variation on deck-building with a highly accurate chemistry theme, with the ultimate goal of building elements to score points, but allowing many varying types of strategies.
Subatomic: An Atom Building Game supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Subatomic: An Atom Building Game is 40–60 minutes. This is the publisher’s estimate for a full game.

Setup and teaching time are not included in this estimate.
