Sumward — Number Roguelite Deckbuilder

How it plays

Clear rules, real identity, and a reason to improve.

Patterns are points

Play hands that form pairs, runs, sum-to-ten, or prime sets. Each pattern scores chips times a multiplier — find the overlap and the numbers explode.

Stack relics until it breaks

Clear a round to reach The Exchange: twenty-two relics, number packs, foil/holo/gild enhancements, and a deck shredder. Build a deck that snowballs out of control.

Bosses that change the rules

Static Field at round 4 takes your discards; The Auditor at round 8 scores junk hands at zero. A boss lands every round from the third on, and your deck has to answer the question each one asks.

Then go infinite

Beat eight escalating rounds and the run keeps going. The only ceiling is how hard you can make the math break.

Why we built it

Sumward exists because deckbuilder roguelites are perfect engines for 'just one more run' — and arithmetic patterns are a synergy language everyone already speaks.

Who it is for

Roguelite deckbuilder fans — anyone who lost a week to Balatro — who like synergy-stacking, run variety, and big satisfying score swings.

How a run works

Draft → play patterns → score chips × mult → shop the Exchange → stack relics → break round 8 → go infinite.
