Gatecraft
Begin with one humble NAND gate and rebuild all of boolean logic, gate by gate, until you can match any truth table.
How to play
On a wiring workbench you place gates, connect their ports, and aim to make the output reproduce a target truth table. The campaign walks a tech tree: build NOT from NAND, then AND, OR and XOR from the gates you have unlocked, before a final free-form target level.
- Place an unlocked gate from the Parts panel onto the board
- Click an output port, then an input port, to draw a wire (no loops allowed)
- Verify to check your truth table row by row; unlock each gate to add it to your parts
Controls
- Desktop: click Parts to place gates, click port-to-port to wire, right-click a gate to delete it, then press Verify
- Phone & tablet: a mouse is recommended — wiring and right-click delete are easiest with a pointer
Game modes
- Daily: a shared final-level truth table seeded from today's date
- Practice: a fresh randomized final target each run
Tips & strategy
- Feed one signal into both inputs of a NAND to make a NOT
- Build XOR by combining the AND, OR and NOT chips you already unlocked rather than starting from raw NANDs
What you'll learn
Gatecraft teaches functional completeness — how every logic gate can be built from NAND alone — a deep idea made playable.
- Skills: logic gates, Boolean logic, functional completeness, digital design
- Best for: roughly grades 9–12 (ages 14+)
- For parents & teachers: how all logic builds from one gate.
