CATCULUS: Neon Arithmetic

About

CATCULUS: Neon Arithmetic is a fast mobile-friendly memory puzzle remix inspired by the MIT-licensed js13k game Catculus. Watch the number grid, memorize the tile positions, then tap hidden tiles that add up exactly to the target sum. Every perfect solve builds your combo, extends your score, and throws you into a harder round with less time to think. Use one Recall Scan per round when your brain buffer melts, but spend it carefully. Controls: Mouse / touch: Tap tiles and buttons. Keyboard: Arrow keys or WASD to move focus, Space / Enter to select, S to scan, Backspace to undo. Mobile: Fully touch-ready. Tap tiles, use SCAN and UNDO from the bottom bar. How to play: 1. Memorize the glowing number grid. 2. When the tiles hide, pick tiles that add up to the target. 3. Do not overload the sum, or you lose a heart. 4. Clear rounds quickly to build combo and beat your best score. Remix notice: Inspired by Catculus by Antti Haavikko, 2025. Original project licensed under MIT. This remix uses new code, new UI, new mobile controls, and a new neon cyber-cat presentation.
