Using the rotation buttons will have no effect besides creating a sound. This allows to charge Delayed Auto Shift for the next Tetromino. Inputs during line clears are not ignored.When starting on level 0, it's 90 lines to level 9, 110 lines to level 10 and 310 lines to level 20. This is independent from the start level: When starting on level 9, it's only 20 lines to level 10, but 220 lines to level 20. From level 9 to 20, it's 20 lines to the next level. Level progression differs: From level 0 to 8, a player has to clear 10 lines to reach the next level.In A-TYPE, the player needs 50,000 less points for the rocket starts (50,000 points for small missile, 100,000 for medium, 150,000 for big).It features the song 'Minuet', while version 1.1 features 'Korobeniki'.In Japan, where no game game was packaged with a Game Boy, Tetris sold as well as Super Mario Land (around 4.2 million copies).Īround 10,000 cartridges of this prototype version were produced in Japan. 23 million copies were sold in North America alone, because it was packaged with every original Game Boy there. With 30 million copies worldwide, Tetris is the second best selling Game Boy title after Pokemon Red / Blue. Henk Rogers takes responsibility for this randomizer. The relative frequencies should be as follows: As a result, piece shapes containing many zeros appear less frequent. So the chance of getting 2 L pieces in a row is reduced significantly. Then, another L will be rejected in the condition no matter of the locking piece (XXX OR 000 OR 000 = XXX ). Let's say our preview piece is a L (000). Piece shapes containing many zeros in the bitwise notation are rejected more often. Otherwise, choose another piece and use it as the next but one piece (no matter if the condition is fulfilled or not). Accept it as the next but one piece if the condition is fulfilled this time. Otherwise ( locking OR preview OR chosen = locking ), choose another piece (can be the same as before). Hand it out as next but one piece, if the bitwise OR of the locking piece, the preview piece, and the chosen piece differs from the locking piece. The following happens:Ĭhoose a random piece shape. The result has a 1 at a certain digit if at least one of the 2 arguments has a 1 at the same digit. This is an operation that takes 2 binary numbers to compute a new binary number. Pieces are numerated from 0 to 6, repectively from 000 to 110 in binary notation. However, the randomizer works differently in practice. It was intended that the randomizer reduces the chances of getting one and the same piece shape 3 times in a row. When completing level 9 + height 5, a Buran shuttle launch is shown additionally. The number of dancers increase with the initial height level.

In B-TYPE, a screen with Russian musicians and dancers is shown when completing 25 lines on level 9. In A-TYPE, a missile launch is shown when the player surpasses a certain score. The 'heart levels' (activated by holding Down+Start at the title screen) are as fast as the level plus 10, but unlike on the NES version, they don't improve the score. On the other hand, softdrop points are not multiplied by the current level. On higher levels, those points are multiplied by (level + 1). On level 0, the player gets 40 points for a Single, 100 points for a Double, 300 points for a Triple and 1200 points for a Tetris. After this, the level advances by 1 for every 10 lines In Marathon (called A-TYPE), when the player line clear (startLevel * 10 + 10), the level advances by 1. For example, level 1, or 49 = 31h frames, is stored as 30h. This table is located at 1B06h in the ROM each entry is one less than the actual number of frames.

DAS: 23 frames for initial delay, 9 frames for autorepeat.

ARE: 2 frames (tetromino is invisible for first frame after it spawns).

Game Boy runs at 59.73 frames per second. This page does not have language versions.IPad 3, iPad 4, iPad Air, iPad iPad, iPad Mini 2, iPad Mini 3, iPad Mini 4, 9. IPhone 14 Pro Max, iPhone 15 Plus, iPhone 15 Pro Max: 1290x2796 IPhone 12 Pro Max, iPhone 13 Pro Max, iPhone 14 Plus: 1284x2778
