Commodore 64 Port • oscar64 • PAL

Connect 3. Compact.
Cascade.

The classic logic puzzle ported to the Commodore 64 — VIC-II colour, SID music, and floppy-disk high scores.

Not a Tetris Clone

No tetrominoes, no rotation. A single coloured cell descends a narrow 4 × 12 well. Landing it connects lines of 3 or more matching cells — horizontal, vertical, or diagonal — which vanish, collapse under gravity, and chain into compounding cascades!

Title & Menu

Play, high scores, how to play, and settings.

Six VIC-II Colours

Identical brick shape — colour is the only tell.

Flash Elimination

Matched lines flash white before they cascade.

Floppy High Scores

Top 5 with initials, saved via KERNAL to disk.

50 Hz Logic Engine

Faithful match resolution, gravity compaction, and cascade chains on real 6502 code.

1541 Disk Saves

Persistent minitris.hi on the .D64 via standard KERNAL routines. Use the disk image for high scores.

SID Soundtrack

Memory Reboot arranged for SID by DJ Space, sharing the chip with in-game sound effects.

Real Hardware

Runs on PAL C64/128, MiSTer, Ultimate 64, Kung Fu Flash, SD2IEC, VICE, Denise, and Hoxs64.

How to Play

Master the rules, exploit cascading gravity, and chase high scores on floppy disk.

Single Cell Drop

Coloured cells descend one at a time down the 4×12 well. Position each cell before it settles.

3-Way Line Matching

Connect 3 or more same-coloured cells in straight lines: vertical, horizontal, or diagonal.

Compacting Cascades

Matched cells vanish and floating cells collapse down. New lines trigger compounding cascade multipliers.

Results & Initials

The game ends when the top row fills. Enter three initials and save the run to floppy disk.
