Super Mario Bros. 3 Tips

Easy Way to get Lives!
In World 7, Pipe Land, go to the fortress level. The one that has a lot of blocks in the start. If you are big Mario or any suited Mario, jump at the fourth column of blocks. (the blocks that are at the bottom middle) And hit the highest one which will have a P-Switch. Hit it and all the blocks turn into coins! You can get up to 2 lives on this! Once the effect is finished, go to the door at the bottom and then return. All the blocks will return! Repeat this over and over and you can get infinite lives! My tip is to not beat this level at all. You don't need an item to start out for you can go to the door at the very right from the second room and get a Mushroom from one of the blocks there.
