League of Legends Daily Fantasy Esports is an online contest where you compete against other fantasy players by creating your own lol fantasy team.
A contest is usually made up from two or more Lol matches. You pick five players for your team roster, from the group of players playing in these matches. You can only pick a maximum of 3 players from any given team and you must also pick a player in each of the positions, Top, Jungler, Mid, ADC and Support.
When the esports matches start, the players you pick in your team roster score points based on the actions they do in the match. For example when players make kills they score points, when they die they lose points. The full list of how players score points can be found within the contest page.
Your roster is pitted against the rosters' of other users who have joined the contest. If your roster scores the highest points you win a share in the contest prize pool.
You are given 100,000 to spend on your team, this is the salary cap limit. Each player has a purchase value ascribed to them. The better the player, the higher the cost. The total cost of your team roster must be under the 100,000 salary cap.
