The historic $1.6 billion Mega Millions jackpot had people scrambling to purchase lottery tickets, including many people in office settings.

And for those who threw their $2 into a work lotto pool, here are some cautionary tips.

First, a leader should be named who is charge of the pool and buying tickets.

Next, create a contract that is signed by everyone contributing to the pool. That contract should be made public -- if you win you don't want to split the pot with people who weren't involved.

Copies should be made of the lotto tickets, which should be kept in a safe space.

The odds of hitting all six Mega Millions numbers are 1 in 302.5 million.
