stack it up
land every trick in a growing stack, then add your own
how it works
a rider sets a trick. the next rider must land every trick before it plus a new one, all in a single line. stack it up (SIU) grows with each rider.
consistency wins
as more riders add tricks, the line gets longer. every trick from the history must be performed in order. it's a test of consistency and memory.
how it's different from back it up
in back it up, you only need to land the last trick before adding a new one. in stack it up, you land the entire stack -- every trick from the beginning -- before adding yours.
when does it end
when riders find the stack too difficult, they vote to archive the round. after enough archive votes, the round ends.
archive votes
any signed-in rider can cast one archive vote per round. when the community is ready to move on, the round gets archived and a new stack can begin.
active vs archived
browse current active games or past archived rounds to see how far the stack got. multiple stacks can be active at the same time.
rules
you cannot stack your own trick. you have to wait for another rider to go first.
