About this game
Game Overview
Summoner's Pieces is a new kind of competitive game that fuses
puzzle mechanics, deck-building, and auto-battler elements.
The rules are simple:
Drag pieces from your hand onto the summoning board. When all the tabs (凸) on a piece are successfully connected, the unit or spell sealed within that piece is summoned onto the battlefield.
Piece Types
The more tabs a piece has, the harder it is to summon — but the stronger it becomes.
If your deck is filled only with powerful pieces, it will be difficult to summon them. Make sure to balance your deck with weaker pieces too.
Pieces come in five elemental colors, each with unique tab-and-slot shapes.

There are also neutral pieces with no elemental attribute. They consist of common shapes only, making them easier to include in any deck.

Some pieces are spell pieces that activate an effect immediately when summoned.

Auto-Battle
Once summoned, units with various abilities will automatically battle each other. The player who eliminates all opposing units wins.
All you need to do is “solve the puzzle to summon” — no need to learn complex rules.
As you get used to the game, you’ll discover deeper strategies through timing your placements and building your deck.
Rules
Place a Piece – Drag a piece onto the summoning board
Connect All Tabs – Once all tabs are connected, the sealed unit or spell is summoned
Auto Battle – Summoned units fight automatically; the player who eliminates all opposing units wins
