General Differences
- No music plays at the title screen, or when the Game Over graphic shows up.
- Pausing in-game doesn't mute the music.
- Loginska in this point of development sounds unfinished, lacking the second half of the song.
- In main menu, the only options are 1 PLAYER and 2 PLAYER.
- You can only choose starting levels from level 0 (Beginner), level 3 (Intermediate), level 6 (Advanced) and level 9 (Expert) as starting levels as opposed to 0-9; and cannot enable handicap/height/round at all (or straight up, handicap/height/round doesn't exist yet compared to later builds).
- There's no bonus screen. Instead, the game just continues.
- Lines will clear instantly with no visual effects.
- Levels are increasing every 10 lines, not 30.
Graphical Differences
- The O, I, and L pieces share the same graphics throughout the remaining prototypes, but the T, Z, and S pieces' graphics were different compared to other, later builds, the J piece using a darker shade of green compared to other builds, and the S piece's graphic being used for the T piece in later builds. Surprisingly, the diagonal piece graphics can be found in the CHR data in Prototype A, although unused.
Prototype A | Prototypes B to Vs. System |
---|---|
- The Game Over text has a blue border.
Title Screen
Prototype A | Prototypes B | Prototypes C to D |
---|---|---|
Vs. System (Vs. Tetris) | Final |
---|---|
- Unlike later builds, Prototype A's title screen is much simpler, lacking a border, the texts TENGEN PRESENTS and THE SOVIET MIND GAME, and has a rather unfinished looking backdrop. Surprisingly, the R in TETRIS on the title screen is not Я (ya), compared to later builds and the final game (and Vs. System).
- There is also ALL RIGHTS RESERVED. and LICENSED BY NINTENDO OF AMERICA INC. on the title screen.
Unused Graphics
- In the CHR data, lies these 19 (one duplicate at the end of the top row of unused graphics) unused block tiles that aren't used anywhere in game.
