Deduce Dock

Logic and ReasoningLogic GridsGrades 3–6Keyboard

What students practice

Students practice solving logic grid puzzles, reading a set of clues to deduce which ship carries which cargo, or who has which job or pet, marking a grid square with an X for no or a locked O for yes, where a lock crosses out the rest of its row and column, with clue types and grid size set by a teacher.

How to play

Players use the arrow keys to move and the space bar to mark a square (press once for X, again for a locked O, a third time to clear it), then press Enter once every row has a lock. A wrong berth, or a convoy that arrives late, costs a shield, and three lost shields ends the mission. A miss has the machine show the correct berths and the clue that proves it before that puzzle returns later.

Teacher Setup

Teacher Setup lets a teacher choose which clue types are in play (starting with is/is-not clues, or all four types), the grid size and story theme, and the speed. The end-of-mission report includes a printable list of skills to practice.
