GateForge
Build logic circuits and watch them light up (ages 9-14). Wire AND/OR/NOT/XOR/NAND/NOR gates together, flip the switches, and see the truth table come true - digital logic from a single gate up to adders and a tiny CPU. Meet the crew of fireflies who each ARE one gate: Duet glows only when BOTH are on, Orla when EITHER is, Nay flips its friend, Odele lights on a mismatch, Nandi and Norah are the two you can build everything from. On-device, no accounts, no ads.
#0369a1 Distributed-narrative cast
Meet the cast
GateForge is a crew of circuit fireflies who each embody ONE logic gate - the cast IS the curriculum. Wire them together, flip the input switches, and watch the truth table light up. Learning digital logic is learning when each firefly glows: Duet needs BOTH, Orla needs EITHER, Nay is always the opposite, Odele lights on a difference, and Nandi/Norah are the humble pair you can build every other gate from.
Duet
The AND gate - a firefly who glows ONLY when BOTH her inputs are on; one light alone stays dark (the both-or-nothing rule that makes two-key locks safe)
Read chapter →
Orla
The OR gate - a welcoming firefly who glows if EITHER input is on (or both); only all-quiet leaves her dark (any one signal is enough)
Read chapter →
Nay
The NOT gate (inverter) - a single-input firefly who is always the OPPOSITE of his friend: on becomes off, off becomes on (turns a backwards signal right)
Read chapter →
Odele
The XOR gate - a firefly who glows ONLY when her two inputs DIFFER (one on, one off); same-and-same, either way, leaves her dark (the mismatch-finder, and the carry in adding)
Read chapter →
Nandi
The NAND gate - off ONLY when both inputs are on, bright every other time; the humble UNIVERSAL gate you can build every other one out of
Read chapter →
Norah
The NOR gate - glows ONLY when both inputs are off; the smallest spark anywhere sends her dark (the all-clear light; the other universal gate)
