One Card Dungeon is a board game released in 2021 for 1 player, 15–60 minutes per game, and ages 10 and up. It was designed by Barny Skinner and its main mechanics are Dice Rolling, End Game Bonuses, and Square Grid.
One Card Dungeon is a solo dice-placement dungeon crawl played on a single card. Fight through 12 increasingly challenging levels to reach the final prize - the Sceptre of M'Guf-yn. Both the Adventurer and the Monsters are represented on the map by Dice, with the value on top showing their current health. Each room has one type of Monster, with anywhere from 1 to 4 of that monster to defeat in each room. The basic game mechanic is rolling three dice, then assigning one dice to each of your Movement, Attack and Defense. Adding together your skill levels in each of these areas with the dice you have assigned gives you a total number of points in each of these areas to spend, for example if you have a Movement skill of 3 and assign a 4 dice to it, you would have 7 Movement points to spend that turn. After each room, you may upgrade one of your four skills - Movement, Attack, Defense, and Range. —description from the designer
One Card Dungeon 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 One Card Dungeon is 15–60 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 One Card Dungeon for ages 10 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.
One Card Dungeon 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.
