Tel-Tel Stadium (ＴＥＬ・ＴＥＬスタジアム?, "TEL · TEL Stadium") is a Sega Mega Drive baseball video game released in 1990. Along with Tel-Tel Mahjong it is a part of the Tel-Tel series and allows for online multiplayer through the Sega MegaModem and the Sega Net Work System, as well play against computer opponents.
The player becomes the coach as the individual players are not directly controlled. Instead, commands are given for pitching and batting; which may or may not be obeyed depending on the situation. The multiplayer mode is text-only while the single-player game has all the graphics in addition to the text. Thirty different teams are available in this game; with options ranging from actual Nippon Professional Baseball teams to little league baseball teams and even a team of professional wrestlers.
