Flip 9 is a board game released in 2014 for 1 player, 4 minutes per game, and ages 4 and up. It was designed by Chih-Fan Chen and its main mechanics are Pattern Building.
Flip 9 is a solitaire game that challenges a player to organize numbered cards in a row from 9-1. To start, the player shuffles the cards and lays them out in a row. For the first turn, the player takes any two cards, swaps them, then sums these numbers (summing the numbers again if the sum is larger than nine). For example, if the player swaps cards 6 and 8, their sum is 14, and the sum of those numbers is 5. For the next swap, the player must swap card 5 with some other card. If the player places the cards in descending order from 9-1, she wins. The cards in Flip 9 are double-sided, though, and should you become at ease with the basic game, you can advance to the harder one. To start, flip half the cards to show the other side, then lay them out in a row. Each turn you'll still swap two cards, with every swap after the first having one of the cards being determined by the sum of the previous swap — but now you must also flip over the two cards being swapped. To win, you must place the cards in descending order from 9-1 and have the same side face up on all of the cards.
Flip 9 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 Flip 9 is 4 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 Flip 9 for ages 4 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.
Flip 9 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.
