FLAG-O-TRON is a new kind of deckbuilding with flags and chess pieces.

Easy to pick up, deeply tactical as it unfolds — a flagbuilder that combines the recognizable structure of a roguelike with an original combo-building mechanic, offering dozens of unique decisions in every run.

No cards — just flags. No hand — just a board, where you create winning combos.


Every turn is a decision. Every combo is a step toward victory — or defeat.

Use chess pieces to move flags across the board, unlock new slots in the shop, and upgrade your deck.

Build your strategy, boost your flags with modifiers, discover rare upgrades, and create high-value chains.

At the end of each round, you’ll face a boss. Who it’ll be is a mystery — maybe one that wipes all upgrades from your active flags. Or one that turns every piece into a pawn, cutting off your control.

Each boss comes with unique effects and interferes with the core mechanics, changing the rules mid-game. Sometimes they’ll block movement, reset your score, strip away upgrades, or destroy key parts of the board. With every encounter, you’ll need to rethink your strategy on the fly — adapt or lose.

FLAGOTRON offers a structured, well-designed gameplay loop with high replayability.

Features:

•  Tactical flag placement and thoughtful combo-building

• Chess piece mechanics to interact with the board and unlock progress

• An upgrade system that changes flag properties and point output

• Between-run progression and expanding pool of available tools

• Bosses with unique debuffs that reshape each run

• High replayability: every run brings new conditions, choices, and strategies

• Discover your own path to victory — through upgrades, risk, precision, or unexpected synergies

Every run is a fresh set of rules, chances, and choices.

There’s no universal strategy — but there’s always that one move that can change everything.
