Start with a standard 52-card deck and a score target to beat. Play poker hands -- pairs, straights, flushes -- and watch the chips multiply. Then add joker cards that break the math wide open: a joker that triples all hearts, one that adds chips for every face card played, another that retriggers the last card in your hand. Stack jokers together and a humble two-pair suddenly scores 50,000. Planet cards level up specific hand types. Tarot cards transmute your deck. Spectral cards bend reality. The blind system keeps raising the target, and your job is to build a scoring engine that outpaces it.

Summer Engine helps you build this loop through conversation. Describe the jokers you want, the card transmutations, the blind escalation curve. The AI sets up the scoring pipeline, the shop system, and the round structure while you focus on designing joker interactions that make players say "wait, what if I combine THESE two?"

Balatro proved that deckbuilders do not need combat. The tension comes from math, from stacking multipliers, from watching a carefully constructed scoring engine either clear a blind by a hair or collapse spectacularly. That is the feeling you are here to build.

• Solo devs who want to build a scoring-focused deckbuilder without writing a combat system.
• Designers fascinated by emergent math -- how simple multiplier rules create explosive combos.
• Anyone inspired by Balatro, Luck be a Landlord, or Stacklands who wants their own spin on the genre.
• Developers aiming for a viral loop where players screenshot their insane scores and share them.

• Joker Design Lab

  Get a working poker-hand scoring system running so you can rapidly prototype joker effects, test multiplier stacking, and find broken combos before players do.

• Mobile-Ready Roguelike

  Build a session-based game perfect for mobile. Short runs, quick decisions, no complex combat animations. Pure strategy in a small package.

• Viral Score Chaser

  Create a game where every run produces shareable moments. Big number screenshots, absurd joker combos, and the "one more run" hook that drives organic growth.
