The WWE Royal Rumble is one of the few pro wrestling events you can have a pool for without worrying because the results are rigged.

The main event of  Sunday's pay-per-view show is an over-the-top-rope battle royal, with participants entering every 90 seconds. The last man standing gets a world title shot at WrestleMania.

Putting a pool together makes the match, which can last more than an hour, much more fun to follow. The options include awarding points based on how long a participant stays in and how many others he throws out.

Pools that draft participants in advance are almost obsolete because the list of entrants is almost never fully revealed. Sometimes the list changes based on matches earlier in the card, too.

The more popular pools involve drawing numbers. Whoever comes out at that number is who you get.

The pools that award points based on how many others one throws out are for the die-hard fans. When there's a scrum near the ropes, you need a spotter to call out who's doing what and someone else to write it down.

Our group from the office does a pool, but we we're not as labor-intensive. Here's how ours works:

(Based on five people)
Draw Nos. 1 through 20, four each
Draw Nos. 21 through 30, two each - guaranteeing everyone two of the final 10 evens it out and keeps everyone happy.

First wrestler out - 1 point
Second wrestler out - 2 points
29th wrestler out - 29th points, etc.

The player whose six wrestlers' points add up to the most wins. You just have to root for your guys to stay in the match.
