I have tested and tried to figure out what the secret is to doing a big jump on Springboards in the original Super Mario Bros, but have been unable to figure out what triggers it. The closest theory I seem to have is that you have to press "B" while in the air and then hit "A" as you are jumping, but sometimes I still only do a small jump?
Can someone tell me what the official way to get a big jump is when using these annoying things?
Best Answer
You have to press A when the trampoline is fully compressed, before it sends you in the air. There's nothing else to it, just got to get the timing right.
