ABOUT THE GAME

Create input/output that meets specifications

This is a puzzle where you read input and output specifications and create a circuit that meets the conditions using parts and wiring. The completed parts will be used as materials for later tasks. The posted image includes a wiring example that is the answer to the first Nand challenge.

01

Place the parts and connect the terminals

Drag the parts from the toolbox onto the board and place them. Connect the wires from the triangular terminals and switch the input switch to change the state of the circuit.

02

Compare with the specifications in the table.

Each assignment has a table showing the input and output combinations. The circuit you created will be evaluated using "Check Answer" and if all the conditions are met, the task will be completed.

03

Use the completed circuit as the next material

The created component will be used in subsequent assignments. The stage list includes logic gates, arithmetic, switching, arithmetic logic units, memory, and processors.
