About this game
Magic isn't memorized. It's computed.
In (Spell+Fract), every spell you throw is a small puzzle. Chain symbols and mathematical formulae into a live cast, and the quality of your solution decides everything — the power, the effect, the payoff. Solve it clean and a Frost Orb doesn't just land, it shatters. Fumble the formula and the spell fizzles in your hands.
This is a roguelike where mastery means out-thinking the run, not out-twitching it.
Cast by Solving
- Formula-Driven Casting — Assemble spells from symbols and formulae. Better solutions mean stronger spells — every cast graded live.
- Spellcraft — Combine and refine recipes on the fly. The deeper your understanding, the sharper your magic.
- A Real Toolkit — Turrets, terrain, shields, healing, damage fields, and teleport casting mean every encounter has more than one solution.
Every Run Is Different
- Roguelike Progression — Push your luck through risk rooms, loot chests, bounties, and relics. No two runs build the same.
- Spend Your Spoils — Slot machines and the gold shop turn a good run into a great build.
- Rising Challenge — The further you go, the more the arena demands of your spellcraft.
Make It Yours
- Mod Support — Custom maps, rules, and content packs, with built-in sharing so the community keeps the arena growing.
Solve the spell. Break the run. Out-math the arena.
