GlassDance
You will find this bears a great deal of resemblence to HammerDance :D
Rules
Id think
Option 2 with this one, as time wont make a difference, (just res :D)
Option 1
Each round, will be assigned a glassblowing item. The person with the highest quality item will win that round. it could either be head to head knockout rounds or a full knockout (everyone tries lowest is knocked).
Option 2
Every round, every item possible is made, the lowest combined quality is knocked out.
Option 3
Someone picks a random quality, and an item, the first to get there wins the round. wouldnt be exact quality... 100 eaither i think... or between (8k-9k etc.)
