Bounce blocks are a kind of block in Mega Jump. Their appearance differs in each stage, but all have the same properties.
When stepped on, the Bounce Block will boost the player upwards, with more power than a Coin or a Break Block. Unlike a break block, it is reusable and the player may bounce on it as many times as he/she likes. Like most solid objects, bounce blocks will be destroyed if touched be a character using power-ups (Balloon, Fireball or Supernova).
Spike blocks are obstacles in Mega Jump that will make the character lose coins upon contact, similar to monsters and anvils. Like anvils, they can't be destroyed without powerups. They can be destroyed by Boost Stars and Power-Ups (except Action Umbrella).
Break blocks are a kind of item in Mega Jump. Their appearance differs in each stage, but all have the same properties. They are usually a square block with a design in the middle.
When a break block is stepped on, it will give the character a short boost upwards, however, the design or shape inside the block will disappear. If stepped on again, the block will break and will also disappear, giving the player 2 jumps before the block shatters. Break blocks sometimes have things hidden inside them, which can be Coins, Powerups, Boost Stars, or even Fireballs and Supernovas(the latter two appear less often). Like most obstacles, these will be destroyed in one hit from the Balloon, Fireball or Supernova.
