Gridcannon is a board game released in 2019 for 1 player and 5–20 minutes per game. It was designed by Tom Francis and Chris Thursten and its main mechanics are Pattern Building and Solo / Solitaire Game.
Gridcannon is a solitaire game that uses a traditional deck of cards with jokers. The game was made by Tom Francis and Chris Thursten in 2019. In the game you have a 3x3 grid of number cards and around it you have face cards. The face cards are called royals and the goal of the game is to assassinate all 12 of them. If you manage to do this you win the game. Number cards may only be played on matching or lower numbers. In order to kill a royal, you place a card opposite him/her - which means you have lit the charge on a cannon - and you use the two cards between the trigger and the royal, the "payload", to do that much damage. Payloads can include any suits when attacking jacks, but must match the color of any queens attacked and the suit of attacked kings. Aces and jokers provide you with special actions.
Gridcannon supports 1 player 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 Gridcannon is 5–20 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.
Gridcannon has a complexity rating of 1.5 out of 5 from BoardGameGeek players, which makes it a 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.
