To win at level 25 (Tic Tac Toe), start at any corner. The purple duck will go in the middle. Go in the opposite corner of your first one. they will choose either corner. You will have doubled him.
I found a trick for defeating Waizer! You will need the skill 'Piercing', under the group 'Potency'
and just keep using. It will stun Waizer and he won't be able to counter-attack you.
Put a limit/cap on spells. The 2nd boss stuns you like 200 times in a row. Than "Yug IronFlesh" heals everytime you get his health below 50, and it turns into an hour wait game.
When your on "Evil Droid" Mode, how do the droids know you're there? They start shooting as soon as you walk near the wall that's suppose to be blocking you from it...
