In "Boss Fighters QR" up to four heroes team up to face ten distinct boss monsters, each run by an app that reacts in real time to player actions. At the start of every showdown the bosses' tactics and abilities are completely hidden, pushing the group to observe, deduce and uncover weak points before striking. Each player selects a hero deck – Jungle Troll, Hill Halfling, Copper Dwarf or Wood Elf – and pairs it with one of four classes (Warrior, Mage, Rogue or Druid), granting variable powers across the party.

The Scan&Play mechanic lets you scan your cards with a smartphone; the app instantly recognises the play and triggers the boss' response, creating a dynamic action queue. When a boss falls, the heroes open three secret loot boxes and claim loot cards that upgrade their decks, unlocking stronger abilities for the next encounters. Every battle can be attempted on four difficulty levels, scaling the bosses' tactical depth. The game blends deck‑building, hand management, deduction and pattern recognition within a cooperative fantasy campaign. With an average playtime of 40‑60 minutes and a light weight (2.08), the experience is approachable yet offers enough strategic depth to keep the group invested throughout the entire campaign.
