IQ XOXO is a fun logic game that gives players the goal of filling a grid using 10 colorful, double-sided pieces. Included with the game is a folding travel game board, 10 differently shaped pentomino puzzle pieces with alternating “XOXO” faces, and a booklet with 120 different challenges and their solutions. In order to successfully fill the grid, the player sets up the given pieces as shown in booklet and then uses the remaining pieces to fill in the rest of the board. The game provides certain constraints, however, as the game board is constructed to force letters to alternate, so that two X’s or O’s cannot coincide vertically or horizontally. This game promotes engineering thinking and design by encouraging the user to come up with a solution to a problem while satisfying a given set of constraints. In addition, it also encourages creative thinking and spatial reasoning. Since the challenges get progressively harder, the game consistently promotes the improvement of these skills.


Engineering thinking and design practices the gift encourages children to do or learn about: Define a problem, generate ideas, plan the solution, try the solution, redesign the solution, recognize patterns

Engineering text or context explicitly provided by the gift: A problem, criteria, constraints

Additional practices and skills needed by engineers that were addressed by the gift:

Spatial reasoning, critical thinking, creative thinking, design, problem solving
