Begin with one humble NAND gate and rebuild all of boolean logic, gate by gate, until you can match any truth table.
Was this fun?
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
