"When Rummy meets Roguelite, space is your greatest resource—and your tightest constraint."

Rummy Attack!!

A fresh take on the Roguelite Card Battler, powered by Rummy rules!

Play cards onto the field to create "Melds"—Sets of the same rank or Runs of consecutive numbers—to unleash powerful skills.

Acquire new cards after every battle, build your ultimate deck, and challenge the final boss!

Key Features:

◆ Rummy-Style Combo System (Meld System)

• Drag and drop cards from your hand directly onto the battlefield!

• Combine cards into "Sets" (three of a kind) or "Runs" (same suit, consecutive ranks) to trigger various effects like Attack, Defense, and Recovery.

• Even two cards can be placed as a "Potential Meld." Strategic placement is the key to victory—think ahead and set the stage for massive combos!

◆ Strategic Deck Building

• Every character starts with a unique deck.

• Each Suit has a specific role: Swords and Axes for physical attacks, Potions for healing, and Coins for increased rewards. Tailor your deck to match your playstyle!

◆ Battlefield-Shaking "Enemy Gimmicks"

• As you progress, the enemy's interference becomes more ruthless.

• "Ground Fissures": Cracks appear on the field, blocking you from placing cards in those areas. Can you complete your melds in the remaining narrow gaps?

• "Curse of Gigantism": Your cards are forced to grow in size, eating up precious field space! Experience the unique tension of having the right cards but no room to play them.

• Face a variety of other disruptive skills. Will you crush them with high firepower before they move, or build a flexible deck that thrives in tight spaces? Your preparation and intuition will be put to the test!

◆ Diverse Relics

• Boost your Muscle to empower attack cards, or increase your Brain to enhance magic!

• From Critical Rate and Card Size to Magic Range—upgrade various stats through Relics and events to create a truly broken build.

◆ Two Distinct Modes for Your Playstyle

• [Tactical Move Mode]: A puzzle-like experience where every "Move" counts. Plan each step carefully to build maximum melds with minimum movement.

• [Intuitive Time Mode]: A high-speed battle where the clock is always ticking. Can you find the optimal melds in the heat of the moment?
