21 - Play Online
DOS - 1982
For small DOS games like 21, you can play online immediately with your browser (Chrome, Firefox, Safari, Internet Explorer...). This feature is still experimental, the game may not work properly. Warning: game save should work, but you should try it early! Also, be careful to select the right game executable in the list below.
You have to choose the right game executable, then press PLAY.
To exit fullscreen mode, press escape. Playing experience can be poor due to your browser or your computer. Download 21 and launch it with DOSBox to have the best playing experience!
If the game is too fast or too slow, try hitting CTRL-F11 (slower) and CTRL-F12 (faster).
Still no comment for this game.
