Commercial use or distribution. ======== Commercial usage or distribution of Arimaa related products or services require obtaining a licensing agreement from Arimaa.com. The license is obtained by agreeing to share a minimum of 1% of revenue with Arimaa.com and announcing your product or service to the Arimaa community on Discord. This amount is used towards the yearly Arimaa World Championship fund. Post your product or service announcement in the general channel with @everyone. For example: Hey @everyone Zman Games is announcing the release of the Arimaa board game. We will be sharing 2% of the revenue with Arimaa.com. Payments should be sent by the end of January for the previous calendar year using PayPal to arimaa_game@yahoo.com. Any activity in which a vendor charges a customer for a product or service that incorporates Arimaa falls under this category. Even if Arimaa is one part of a larger product or service for which a vendor charges a customer, it is considered commercial use of Arimaa. Also situations in which a vendor does not directly charge the customers for the product or service, but still generates revenues through other means such as advertising or sponsorship, is considered commercial use. Examples of commercial use or distribution: * I want to sell software that incorporates Arimaa. * I want to let people play Arimaa on a game site which generates revenue from customers or advertising. * I want to sell Arimaa board games. * I want to sell a book about Arimaa. * I want to hold an Arimaa tournament where the organizers charges a registration fee, entry fee, sponsorship fees, etc. * I want to hold an Arimaa event where the organizer charges a registration fee, entry fee, sells tickets, receives sponsorship fees, etc. * I want to sell Arimaa merchandise; such as T-shirts, caps, mugs, paintings, etc. * I want to commission a person or company to make an Arimaa product for me; such as a game set, mug or program. This list of examples is not complete; there may be other cases that fall under this category. Basically if there is any transaction involving an Arimaa product or service, then it is considered commercial use. What is granted: * The Arimaa name and branding may be used for informational or educational purposes. * The Arimaa board and piece design may be used. * The Arimaa rules may be used. * The Arimaa game may be implemented.

Non-commercial, non-ERP use or distribution. ======== Some usage or distribution of Arimaa may be non-commercial, but also not fall under the educational, research or personal (ERP) category. For such cases an announcement of your product or service in the Arimaa discord is sufficient. For example: Hey @everyone I am releasing an open source Arimaa game engine on Github. https://github.com/AriaaGameEngine Examples of non-commercial, non-ERP use or distribution: * I want to publicly distribute software that incorporates Arimaa.
