Am I missing something here? It says cumulative total of MGP earned. It says nothing about winning. You don't 'win' the mini cactpot, and you don't have to win the jumbo cactpot. For the mini cactpot, any amount you get counts toward the achievement, whether you get less than 100 MGP, or 10,000 MGP. It all goes towards that achievement. For the jumbo cactpot one, any amount you get counts towards the total. You don't have to get 1st. Even the consolation prize counts towards it.
