Isaac is a board game released in 2011 for 2 players, 15 minutes per game, and ages 8 and up. It was designed by Emiliano "Wentu" Venturini and its main mechanics are Tile Placement.
Isaac is an abstract strategy game for two players. The game is divided in two different phases, placement and scoring. During the placement, a player places one of his rectangular pieces on the available spaces of a 10×10 square grid board. During the scoring, each player removes one of his pieces from the board, scoring a number of points equal to the number written on the removed piece times the number of pieces that lie on the row/column from which the piece was removed. A piece can be removed only if it is at least long as the longest piece already removed by the same player. Each player uses his/her own counter to keep track of his/her points but the counter itself is placed on the board (that is, the board is also the score track). The presence of a counter on the row/column from which a piece is taken doubles the points scored. A player can decide to score less points than he/she earned, therefore allowing to place the score counter in a more convenient place. You can play Foundations and Hari with an Isaac set.

Isaac 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 Isaac is 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 Isaac 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.
Isaac has a complexity rating of 2.3 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.
