At its heart Bust A Move Deluxe is a simple puzzle game, match bubbles, get 3 or more and they vanish...more pop really. You can bounce your bubbles off the walls to make those trickier matches. They also throw in objects you can't just pop away. Let me tell you it took me a couple of times to beat that round.
But add in 6 specialty bubbles that can do anything from making an entire color vanish. To blast your way through a part that you find a royal pain. The game is highly addictive fun.
I played Classic Mode, which is just 1 of 10 variations of the game. Some of which I swear would even give those who normally fly through games...real problems. Like one shot wins, land your bubble in the exactly right spot you win...otherwise you lose. Is impossible for me.
Not to say all of them are bad, Mix Em Up, where the bubbles randomly change colors...is fun. It makes more of a challenge. Then there is Time Warp, where your game either speeds up or slows down is also very fun.
If your still unsure check out the vids of this game on YouTube.
