Power-on pattern

A Power-on pattern is a sequence of pieces that remains the same when a system is power cycled. The first notable game to have such a pattern is Tetris (Sega).

Tetris (Sega)

Sega Tetris pays homage to this pattern during the credit roll, the playfield is cleared and the power-on pattern is given.

Opening perfect clear

Flash Point

Flash Point also contain a power-on pattern, and uses it for every level you play for the entire game, and if you continue. If you fail to continue, the next game continues where the failed level ended in the power-on pattern. Again, unless you are playing a bootleg without NVRAM, you must clear the NVRAM to get the power-on pattern back.

Bloxeed

Bloxeed contains a power-on pattern as well. Additionally if you "continue" you will receive the pieces in the same order again! However, the powerups are NOT included in the power-on pattern, and are truly randomized.
