Sigmally provides a browser-based Agar.io private server where players can play the game, with a shop and Sigma Pass.
About Sigmally
Sigmally is a browser-based private server for Agar.io, a game in which players grow by eating pellets and smaller players. The site includes a PvP mode, server choices (US-1, US-2 and Europe-1), a skins menu, and a shop offering gold and Sigma Pass. Players can play as a guest. Registration is required to save progress, and sign-in uses Google.
The homepage describes the game as modded, with players moving faster, cells having larger mass and players losing mass faster. Pricing is not listed on the source page, so the cost of the shop and Sigma Pass is unknown.
