HOW TO PLAY
Controls and goals
- How to operate
- Drag and place the parts with the mouse and connect the wires from the triangular terminals. Click the input switch to toggle between 0 and 1, and check the answer by clicking "Check Answer".
- Goal
- Create parts that meet the input/output conditions specified by each task, and use the completed parts to proceed to the next circuit.
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.
GAMEPLAY
Signal changes depending on input combination
The following contains sample answers to the first Nand assignment. A and b at the bottom of the screen are input, and the lamp above is output. A state in which current is flowing is displayed as 1, and a state in which no current is flowing is displayed as 0, and the signal can be tracked using the wire color and numerical value.

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.
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.
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.
PLAY NOTES
Play notes
- How to get started and language
- Select "Japanese" at the top, close the explanation, and start with the first Nand assignment. You can read the supplement in "Stage Tips". The assignment explanation is in Japanese, Input is the input, Output is the output, and Toolbox is the parts box.
- Necessary knowledge
- The official guide states that no prior knowledge of computer configuration or software is required. Regarding mathematics, while it does not require skills beyond addition and subtraction, there are some assignments that require time to think.
- Estimated time
- Officially, the required time in minutes is not indicated. It consists of assembling a circuit step by step using multiple tasks.
- Fees and environment
- You can play the PC browser version of the official website for free. The site has instructions for voluntary donations.
From the input/output conditions,
Let's assemble the circuit.
