How to unlock the Die Hard achievement in Tetraminos - Definitive Guide
Danger appears every time you reach the top 4 rows of the field. The music changes and the screen gets red to show you that you reached "Danger". Delete rows to clear Danger and start stacking pieces to the top again. Repeat that 5 times in one game of Endless mode.
