A top out occurs when:

  • a tetromino cannot be placed at least partially within the play zone.
  • garbage pieces are sent, pushing the top pieces above the spawn zone.

Top outs result in a game over.

Loss condition

There are several variations of what constitutes a top out:

  • Block out: a piece is spawned overlapping at least one block in the playfield
  • Lock out: a piece locks when it is entirely out of bounds (that is, in the vanish zone above the ceiling)
  • Partial lock out: a piece locks when it is partially out of bounds, even if it would clear a line
  • Garbage out: After lines are cleared and garbage is added, a block remains out of bounds
  • Top out: an existing block in the field is pushed to 41st or higher row by garbage lines sent to the player
