Margin of Error is a roguelike deck-builder fused with math puzzles, where every card you play could lead to triumph… or total failure. Build equations with numbers and operators to defeat enemies, withstand unique debuffs, and climb your way to the highest score. Will you trust your logic or gamble on luck?
BUILD YOUR DECK
You will start with a variety of math cards that appear randomly ranging from numbers 0–9, basic operators like +, –, ×, ÷, to special cards such as π and square roots. Each run can deal you a different combination. At later stages, you can even build formulas shaped like squares, triangles, and even the golden ratio to unleash greater damage.
FACE UNIQUE ENEMIES
Enemies don’t just have HP—they fight back with debuffs that twist your calculations. Every battle feels different.
STAMPS & MODULES
Power up your run with Stamps (permanent buffs) and Modules (situational bonuses). Will you build a stable equation engine, or gamble on high-risk, high-reward combos?
THE GACHA GAMBLE
Between rounds, you’ll face the temptation of gacha. Take the risk for a chance at epic effects or pay the price when luck turns against you. It’s not just math; it’s courage under pressure.
