Croquet non-poison ball that roquets a poison ball has the normal options. A poison ball that hits a stake or passes through any wicket (possibly by the action of a non-poison player) is eliminated. The last person remaining is the winner. This version of the game was invented by John Riches of Adelaide, Australia with help from Tom Armstrong in the 1980s. The game can be played by up to six people and is very easy to learn. For this reason it is often used as a stepping stone to association croquet. Ricochet has similar rules to association and garden croquet,
Croquet Project architectures that have been developed for the system. Because of this, Croquet has the ability to keep running while code is modified and tested, while changes are made, an essential part of the Croquet collaborative development ability. Users can change the code running the environment while the environment runs. Croquet's time-based synchronization abilities enable real-time, identical interactions between groups of users while dramatically reducing the need for server infrastructures to support virtual world deployment. Croquet's architecture makes it easy to develop deeply collaborative applications without having to spend a lot of effort and expertise in understanding how replicated applications work.
