CebRunner vs Logic Gates

Two gates. Two math operations. One leaves your crowd bigger — and which one flips depending on how many you have right now. Most number-runner games let you coast: multiply usually wins, so you stop thinking. Cebrunner won't. A gate like x3 beats +20 when your crowd is small, but +20 pulls ahead once you're tiny — so you read the numbers and decide in the half-second before the gate arrives. WHAT YOU DO - Drag your crowd left or right to pick a gate. The operation applies instantly. - Watch the crossover: the better choice changes as your crowd grows and shrinks. - Clear the walls. Each needs a minimum crowd — drop below it and the run ends. - Go as far as the math lets you. Difficulty scales with distance. WHY IT READS CLEARLY Your crowd is a single number drawn as tiered shapes: ten triangles merge into one square, ten squares into a pentagon, and so on. A crowd of thousands still fits on screen and stays countable, with the exact number shown as you run. BUILT TO KEEP - Earn coins every run, buy upgrades, and unlock neon themes in the shop. - A short interactive trainer teaches the whole game in seconds. - Accessible from the start: reduce-motion, a haptics toggle, and a colorblind-safe palette. - Plays offline, one-handed, in quick sessions. No timers between runs, no wrong-answer punishment screens — just you, two gates, and the arithmetic. How far can you run before the math catches up?

Wire switches to gates, gates to the bulb, and watch real logic come alive. Logic Gates teaches you how computers actually think — not with videos or flashcards, but by letting you build every circuit yourself. Each puzzle gives you a truth table and a handful of gates. Drag wires, flip switches, test every row, and light the bulb. When it clicks, it stays clicked — because you built it. LEARN ALL SEVEN GATES Start with a single AND gate and work up to multi-stage circuits that use everything: AND, OR, NOT, XOR, XNOR, NAND, and NOR. Six chapters, 34 puzzles, completely free.
