Even though the original Nintendo Tetris® was only released in two regional versions (for NTSC and PAL television standards), Fairtris has four base versions. The additional two versions are modifications of the original ones, with different DAS speed and improved gravity. In addition, each base region has an additional, extended version that has the correct line count calculations for the transitions. Thanks to this, no matter what level you start from, killscreen always occurs at 290 lines.

Changing the region in the Set up game menu results in an immediate change of the game framerate, which is valid both in the game scene and in all menus. Fairtris has separate sound sets for the NTSC and PAL regions that are respected by the selected game region.

 

NTSC

The NTSC region is the equivalent to original NTSC version, without any major modifications, running at 60 frames per second. Take advantage of this region if you've played the original NTSC before. This version supports a transition calculation bug, so transition to level 19 occurs at 130 lines and killscreen at 230 lines cleared.

The NTSC EXTENDED version is the same but with the correct calculations of the transition lines count. Due to the fact that the calculation bug isn't supported in this region, transition to level 19 is always at 190 lines and killscreen at 290. This makes it possible to get the maxout entirely at level 18, before transition. If you are curious if your skill is enough for such an achievement, check out this version definitely.

 

JAPAN

The JPN region is hypothetical, created as a combination of the NTSC and PAL versions. Gravity is the same as in the basic NTSC version, while the charge time and repeat rate of the DAS function comes from the PAL version. Thanks to this slight change, it is possible to stack higher than usual and also play on killscreen, not only by hypertappers and rollers.

The JPN EXTENDED version also doesn't support the buggy calculation of transition, so transition always occurs at 190 lines, and killscreen at 290 lines cleared. Faster shifting, longer gameplay, more fun.

 

PAL

The PAL region is the equivalent to the original PAL version, without any significant mechanics modifications, works at 50 frames per second. Just like the original, it has a wrong gravity calculation, which makes the gameplay almost half the time due to the presence of killscreen at level 19, with 130 lines cleared.

The PAL EXTENDED version doesn't support the line count bug for transition. While it also has a miscalculated gravity, it doesn't support the error in calculating the number of lines for first transition, which makes the game longer. In this version, transition always occurs at 190 lines, which is equivalent to a killscreen. A perfect stacking gives you the opportunity to achieve the maxout.

 

EUROPE

The EUR region is also hypothetical, based on the PAL version. Just like it, it runs at 50 frames per second and the DAS shifts the pieces at the same speed as original. However, the main modification is the gravity change for all levels, which was calculated based on that of the NTSC version. Thanks to this, transition still occurs at 130 lines (transition calculation bug is supported), but killscreen occurs at 230 lines cleared.

The EUR EXTENDED region is a modification of the EUR version, but with the difference that the transition calculation bug is not supported. Therefore, no matter what level you start from, transition always occurs at 190 lines cleared, and killscreen at 290 lines. Choose this region if you prefer the European version and you are curious what it would look like if Nintendo did not spoil the gravity translation and implement so many bugs in its product for the European market.
