There was a board game I used to like to play back in the 80's that was a series of egg timers that you moved across an hour glass shaped board. It was called Quicksand. (I don't think it was very popular as nobody I know has ever heard of it.)

It was a 2 player game.
Each player had 4 timers that started empty.
You took turns rolling a single die that had (2)1's, 2, 3, (2) S's
You couldn't move a timer unless you had sand actively moving in it. If you ran out of sand the timer had to be moved back to start.
You would roll and move the number of spaces on the die, or if you got an S you would flip a timer...yours or your opponent's. You had to use the S...even if that meant giving yourself less time.
The object of the game was to get your timers to the other side without running out of sand in any of them...they all had to be active at the end of the game.
I have never seen a version that could be played on a pc. I loved this game! It was an idea I had a few years ago to someday make a game similar to this one that could be played on a computer.
Now I am going to be honest...I haven't tried to do this because I don't think I have either the programming skills...or digital art skills...to do something like this yet.
