Spikengo

SpikeNGo tournament is now called Kings.

Underdawgs is now called Pools.

You can have Solo and Team versions of the above.

You have 4 main tourney formats:

sign up as a solo, exact numbers are not necessary
get in line behind a cone, when you are at the front of the cone, the other person at the front of the cone is your temporary partner
find a court that does not have anyone serving and get on deck
serve and try to become a king, if you do its 1 point, if you miss, both of you get back in line (same line preferably so you don't play together again right away)
as kings, score as many points as you can, and then when you're done you go to the score pad to enter your score
get back in line and repeat it again
2 rounds of Kings, then you earn the best partner for playoffs if you made it
you will keep this partner for rest of the tournament

sign up as a team, exact numbers are not necessary usually
when you are at the front of the line, find a court that does not have a team on deck
becoming the kings is 1 point, get as many as you can
missed serve count as a point for you and against you
earn your playoff seed based on your kings scoring

sign up as a solo
tournaments are usually 16, sometimes 24 players (exact)
randomly put into a pool, and you will play mini games with everyone in your pool
based on your win/loss and points scored you will have a chance for playoffs and earn your best partner
keep the same partner for all playoffs
