This topic was around earlier (in May. Type in blongo in the Search window and it will come up) and there were several replies.
The game goes by several names and you can buy the game for about $40.00, OR you can go to the link below and get plans and rules for FREE!!

This one is called "Dandy Golf", but I've seen it as Blongo, Bolo Golf, Ladder Golf, Snake Golf. There may be some variances in "rules" but like "Mexican Train", as long as all players agree to the rules, there shouldn't be a problem.
You can also Google these various names and check out the rules. Some sites have balls or "bolos" of various colors you can order.
Hope this helps.
