Atsumare! Guru Guru Onsen

Atsumare! Guru Guru Onsen is a party game where up to four players compete in various tabletop games. It takes place on a hot spring resort, with lively staff guiding the player through various menus. If there are less than four players a computer will fill in any vacant spots. The game also supports online multiplayer. Players can compete against each other in Mahjong, Shogi, and several card games (7 Narage, Daifugo, and Napoleon). The game features Yukon and FreeCell as single player minigames.

It is one of the first games on a home console to have online multiplayer. The game allows players to compete against each other online with chat functionality via the Dreamcast keyboard. Up to six players can also enter a hot spring to chat with each other. The player must create their own avatar to represent themselves online in the form of a 3D model. There are a variety of customization options including adjusting the avatar's height and hair color. Business cards can also be exchanged containing each player's email and profile.
