Sumward: Number Deckbuilder

MAKE A HAND. BUILD AN ENGINE. BREAK THE MATH.

Number roguelike, math card game and deckbuilder puzzle: draw 8 number cards, play up to 5, and score sets, runs, Sum to Ten, Spectrum and Pure Run for chips x mult. Draft relics, tune your deck, and survive eight escalating rounds.

EASY TO READ. DEEP TO MASTER.

- See your score before you commit a hand
- Read powered signals for a scoring hand, a dead selection, or a round clear
- Keep the complete hand table one tap away
- Read every suit by color, symbol, and name
- Spot overlapping hands and score the strongest pattern

BUILD SOMETHING BROKEN

- Discover 22 relics across common, uncommon, and rare tiers
- Combine relic effects into powerful scoring engines
- Add, enhance, or remove cards in The Exchange
- Upgrade cards with foil, holo, and gild enhancements
- Bank coins between rounds to earn interest - or spend them chasing the perfect build

THE RULES CHANGE AS YOU CLIMB

Every run climbs through eight named rounds. From the third, each round bends a
rule: fewer swaps, a smaller hand, halved coins, or junk hands worth nothing.
Beat The Auditor at Round 8 to win. Your run saves after every action, so you can leave
and continue exactly where you stopped.

ONE SHARED DAILY

Everyone gets the same seeded run each day: the same deal, the same rule changes, and the same Exchange.
You get one ranked attempt, then you can compare your result on the global
leaderboard. The Daily is free for everyone.

THE MARATHON (PRO)

Pro adds a separate board on the same daily deck. Carry it past Round 8 in
Infinite Mode as often as you like: every run counts and your best run ranks.
The Daily itself stays one ranked attempt for everyone.
