All SG-1000 games and even all Othello Multivision games can make use of the SC-3000's built-in keyboard or the optional SK-1100 keyboard for basic controls, and a few games have additional features which are only accessible when an SK-1100 keyboard or SC-3000 is used, namely being able to save/load custom levels. These games are:
- Championship Lode Runner
- C_So!
- Lode Runner
- Soukoban
In addition, these programming utility cartridges can be run on an SG-1000, but only with the SK-1100 keyboard. Most of these are also compatible with the SC-3000.
- BASIC Level II A
- BASIC Level II B
- BASIC SK-III
- Home BASIC
Note that SC-3000 specific titles are not covered here, only games which can be played on an SG-1000.
