A randomization system that selects each element one by one, not re-selecting an element until they've all been selected, wherein this process is restarted. Hence the name, it can be thought of as pulling each element out of a bag at random until the bag is empty, then refilling or replacing the bag with an identical one and repeating the process.
A randomization process named n-bag randomization has n elements (for example, 5-bag randomization has 5 elements, 8-bag has 8 elements, and 14-bag has 14 elements).
Tetris is a famous example of bag randomization. It provides each Tetrimino (piece) once every 7 times.
