New Super Mario Bros. DS

If you loved Super Mario 3 on the NES and Super Mario World on the SNES, then you will really love the New Super Mario Bros. for the Nintendo DS. It is a mesh of both games with a new twist, new power-ups, new levels and the same old classic side-scroller Mario we all grew up loving. Here are some tips and tricks that may help you on your way to defeating Bowser and his minions. PS - If you are looking for all the golden coin locations, I am not listing them here, searching for them is half the fun!

• Play as Luigi: At the 'Select file' screen, keep pressed the L and R buttons and choose one of your saved game files with the A button.
• Unlock World 4: Defeat the boss in the last castle of World 2 as Mini Mario.
• Unlock World 7: Defeat the boss in the last castle of World 5 as Mini Mario.

At the start of each world, you can make a different mushroom house appear, Red, Green or Orange. Each mushroom house has its own prizes inside. To make these houses appear, at the end of any level when you reach the flag, depending on what time is left on the clock when you jump on the flag pole determines which color mushroom house appears.

• Red Mushroom House: Item Block prize, jump on flagpole at x11, x22 or x33
• Green Mushroom House: 1-up Lives, jump on flagpole at x44, x55 or x66
• Orange Mushroom House: Mega Mushroom, jump on flagpole at x77, x88 or x99

Warp Cannons (yes, cannons, not pipes):

• World 3 Warp Cannon: At the ghost house in world 3, jump on the very last switch, run up the stairs (that were created by the switch), jump over the hole, go down the stairs to the left and turn right. Another door should appear next to the other one beneath the stairs. You must reach the door before the switch music stops or it will disappear.
• World 5 Warp Cannon: In the ghost house in world 5, there are three blocks in a row, you will find some hidden blocks above it...
