Go on Main Battle, then Tournament, from the main menu. Put Player 1 as the player you want the achievement for then, put all 3 opponents as "COM-Easy", just to make it nice and , err, easy! Select 2 planets for a quick game.

You should win most/all minigames anyway, as they are exceptionally easy! But if you want to a try a new minigame before you play it for real, just press x at the instructions screen. You can play for real after practise.

For the first round, use your x2 multiplier card.Your oppenents will NEVER use a card on the first go. You will start playing Judgement Tower, so that an EASY 20 points. For the second round, play your Steal Card. You will get someone else's x2 card, so there are some more points. 

Custom Master - 50 points

From Main menu go to Main Battle then custom game. Set it up for 1 minigame of judgement tower. Easy as Pi to one decimal place.

And That's it, for the easy ones, there are about 3 more, which are more tricky, because they involve the xbox live community (which doesn't exist for this game).
