1 vs. 100 is the Nintendo DS adaptation of the game show of the same name developed by British studio ECi, in which a single contestant competes against an audience "mob" of 100.

If the contestant gets the question wrong, the game is over and the prize money is split up amongst the mob.

The contestant can opt to quit with their winnings at any time, or press their luck and continue on.

IGN noted that "You can opt out to 'take the money' after each round but doing so just leads back to the main menu.

[4] Non-gameplay elements, such as graphics and sound received a mixed reception.
