HexDragon, created by Nero Games, is an abstract strategy game for 1-4 players from 8 years up, takes up to 30 minutes in real life and ~60 minutes online. The core mechanic revolves around connecting tangled dragon bodies.
The goal of the game is to score the most points among the players.
Players take turns putting 1 of their tiles anywhere on the board, or using the star token to reserve a place for some of their later turns.
Or you can place your star token instead, which reserves the spot for you. The star token can be used only once per game.
Points are awarded for connections of 4 different kinds:
Dragons score points for players depending on the color of their heads. Loops and worms score for whoever closes them.
The game ends, when the whole board is full or the players agree no one can score another point. The player with most points wins the game.
F - flip a tile or increase a counter
R - rotate a tile 60°
E - rotate camera
0 - to reset camera
