This is a retheming of the board game For Sale. Description from App Store: Some battle for pride, some for glory, but all challengers will have to prove themselves to the mighty dragons in this tournament of the four realms. Tournament Of Dragons is a quick (7-8 min.), light difficulty, family friendly (ages 10+), 4-player turn-based strategy mobile app, nominally about hiring mythical creatures and then having them compete against each other. During the game's two distinct phases, players first bid for the hiring of the creatures, then, after the teams of creatures have been built by the players, they battle one another (through simultaneous play) for the greatest profit and glory possible. The AI was trained through a specially designed Neural Network using Deep Reinforcement Learning, so they learnt the game from scratch with no additional information nor human guidance, and achieved its current state after 2 million episodes. The fully trained AI is so good at this game that it only plays on the last arena (of 4), while partially trained AIs are found scattered throughout the leaderboard according to their level. This means that the different AIs will have different styles and techniques of playing the game as you climb the leaderboard.
