My childhood game

there is an arrangement of blocks floating above a pit of lava, and you had to make it to the end. But the twist was you could only put 1 foot on a block at a time. These blocks were numbered 1-10, and if there were two blocks next to each other, you had to put both feet down on the blocks. you also had this stone you had to throw onto one of the blocks, then you had to pick it up on your way.
