HappyTrailz.io is a Wild West-themed real-time group snake game.
At the start, you'll have a small area of land to eat. The more land you eat, the more gifts you'll get, and they can buy new emoticons. You will also own everything that has been marked out. The game is hard because it's easy to die if you aren't paying attention or are greedy. You only need to touch another player's tail to get rid of him. Also, move diagonally. This will let you make moves and give you an edge over other players. Also, killing someone gives you coins, which isn't much. You can see how much of the field you control in the left corner.
Have fun and good luck!
