DOS Games Discussion

I had played a DOS game in which numbers (in the standard DOS font with no frame around the number) from 1-9 or 0-9 (in different colors) fell from top to bottom, here you could move the falling number right and left. If the number was at the bottom and the same digit (or maybe it was the number 0) was right next to it, you lost, otherwise the number was added or multiplied and counted towards the score.

The playing area covered the entire width of the screen. The sound of the game was made for the old speaker not for a modern soundcard.
Does anyone have any idea what the game was called?
