FIND YOUR FLOW
Start on an empty board and race to clear 40 lines. Up to three new rows after a drop, with timed pressure every 20 seconds. Beat your personal best.
Clear rising blocks and build your score. Each line clear fills the DOPE GAUGE.
Enter when the MARATHON gauge fills. Drop vertical I blocks into glowing gaps for consecutive DOPE clears, as the music crossfades into its dedicated trance tracks.
DOPE TRANCE is a bonus phase within MARATHON. You can also try it from the title screen without recording a score.
HOW TO PLAY
Move and rotate your blocks. A completed line bursts into individual fragments that fall away.
Connected groups of the same color fall. Clear another line for a chain. Plan with NEXT 3 and swap a piece with HOLD.
DOPE TRANCE gives you 24 seconds and up to 12 drops. Aim for the glowing gaps, chain your DOPE clears, then return to your normal board.
