To start playing matches for money you can join one of the frequently organized freeroll matches that Wipido organizes. These are matches that are freely joinable, but have a real money prize.
If you wan't to play normal matches against friends or other Wipido users, you must first put some money into your account through Paypal. Once you have some money in your account you can start organizing or joining regular matches.
You can create your own new match. If you are the leader of a clan you can create clanmatches, if not, you can still create individual matches. The jointype can be either 'open for all' or 'invitation only'. Open for all means that everyone can join, invitation only means that only the people you invite can join the match.
After selecting a game, you can choose a gametype that is applicable for your game. This will fill in the 'amount of players' field with a predefined value, but you can change it to your likings. For an individual game the minimum amount is the amount of players that must join the match, otherwise it will be cancelled. For a clan match the amount of players is the number of player that must play for each clan.
Finally you can choose a stake amount and a payout structure. The stake is the amount of money everybody has to put in the match before they can join. The payout structure determines who wins the money. "Winner takes it all" means that the full prize goes to the first ranked, "Top 3" means that it is split among the first three ranked, etcetera. You can find the full financial details here.
To join an open match click the join button, or the link in the green box on top of the page if you've been invited. On joining, you must pay the stake, so make sure you have enough money in your account. If not; add some through PayPal.
After the match you must fill out the results of the match. You can do that on the page of the match. Do not forget this! You can only enter results between fifteen minutes and three hours after the match time! If you forget this, you can no longer enter results and you'll probably lose any disputes that arise!
It is a wise thing to upload screenshots of the results view of the game to your profile, and add them to the match. These may be used by an administrator in case of disputes.
After the match has been played and if a final result could be succesfully established, the prize, minus a fee, is automatically distributed among the winners.
