Bloxeed is a Tetris variant produced by SEGA in 1990. It features similar gameplay to their 1988 version, where the aim is to achieve a high score by clearing lines; however there are now 2 major gameplay twists to make things more interesting:
- Garbage blocks rise from the floor of the playfield at timed intervals, thus making play more challenging. The garbage rises a row at a time and follows a fixed looping pattern as depicted below.
- Occasionally, Tetrominos will spawn containing a "Power Block", which when cleared will have a special effect on play depending on what letter or number is displayed on them.
- F - "Flicky": A small bird appears (presumably Flicky, from the Sega game of the same name) and descends towards the stack. During its descent, it can be moved left and right, and made to drop single blocks (of which it has an infinite supply) by pressing the rotate button. After landing on the stack, the flicky disappears and normal gameplay resumes. It is possible to make line clears greater than 4 at once, with a corresponding increase in points, and it is also possible to make bravos, with the usual 10x multiplier.
- S - "Shot": Similar to the Flicky, Shot is a small satellite which can be moved left and right during its descent, and made to fire by pressing the rotate button. A single shot from the cannon will destroy one block. Shooting and destroying all blocks in the playfield will yield a significant level-depedent "Good Desune" score bonus.
- B - "Bomb": A bomb appears, which the player can position and drop to destroy blocks in a small blast zone. The bomb is 2x2 squares, and explodes when it would overlap the stack. it destroys the one or two blocks that it would overlap, the blocks immediately below those two blocks, the blocks immediately to the side of those two blocks, and all blocks above those blocks in the same column.
- 16 - "16 Ton": A huge 16 ton weight appears, which the player can position and drop to completely clear 3 adjacent columns of the playfield.
- 4 - "4 Lines": Counting from the top of the stack, the 1st, 3rd, 5th and 7th rows are cleared.
Garbage doesn't spawn when a line is cleared. This delays the garbage spawn. Also collecting a powerup clears the garbage meter, further delaying garbage rows.
Notably, powerup blocks are also introduced on a timer. playing slowly yields more powerup blocks, and thus more chances to obtain bravos with the shot powerup.
