About this game

Circuit Cross is a unique puzzle game that challenges you to think like a computer. Fill in grids with 0s and 1s so that every row and column satisfies its logic gate.

Each puzzle gives you a grid with some cells already filled in and a logic operator assigned to every row and column. Your goal is to complete the grid so that each pair of inputs produces the correct output according to its operator.

The game features six logic operators:
- AND: Outputs 1 only when both inputs are 1
- OR: Outputs 1 when at least one input is 1
- XOR: Outputs 1 when exactly one input is 1
- NAND: The inverse of AND
- NOR: The inverse of OR
- XNOR: Outputs 1 when both inputs are the same

Start with simple operators and work your way up to puzzles that combine multiple gates. Four difficulty tiers let you progress at your own pace:

- Easy: Learn the basics with simple operators
- Medium: Tackle more operators
- Hard: Put your logic skills to the test
- Expert: Only for the most dedicated puzzle solvers

Circuit Cross is:
