Tetris

The falling-block classic, rebuilt for a 52x16 matrix: title screen, ghost piece, line-clear fireworks, a chiptune bed and a high score that survives a restart.

Panel: 52x16 · Opened from the clock's menu, not the rotation

The game

A 10 x 16 well at one pixel a block, centred on the panel. The score and level
sit on the left, the next piece on the right at double size, and a drifting
starfield fills what is left.

• Ghost piece — a dim outline where the piece will land
• Lock delay — a moment to slide a piece into place once it touches down
• Seven-piece bag — every shape turns up once before any repeats
• Speed-up — a level every ten lines, and the music gets faster with it
• Scoring — 100 / 300 / 500 / 800 a clear, times the level; combos and a
  PERFECT bonus for an empty well

Effects

Cleared rows burst outward from the middle and the panel shakes harder for a
bigger clear. DOUBLE, TRIPLE, TETRIS, COMBO, PERFECT and LEVEL banners cross the
panel in rainbow letters. A hard drop leaves a streak behind it. When the stack
gets high the walls flash red. Game over floods the well from the bottom.
