BLOXEED: History of Highest Records

National record progression

Here is the complete list of the progression of Bloxeed's verified national records for most lines in one credit. (As far as I can research. If you find any mistake please tell me.)

The competition of Bloxeed had a category for most scores, but SDI-BOSTON maxed out the score (with 154 lines, Level 56) in April 1990, just a month after the first score was registered in March 1990 (712,076pts. by AEX-ででーん!, in Kashiwa Gulliver, Chiba.).

On autofire systems

It was widely regarded that Bloxeed caused the popularization of customized autofire devices; once the Arcadia magazine featured the history of autofire device of the video arcade game (June 2000 issue, p. 62-). A "synchronized autofire," which receives VSYNC from the game board and switches on and off of a button with timings synchronized to the VSYNC, was a groundbreaking innovation because it enabled players to press a button at the theoretically highest possible speed of 30 times per second. Moreover, players discovered the method of alternating two sync autofire buttons (starting the first button pressed and the second button released results alternately switching a button input 1-2-1-2-...). The alternate sync autofire literally doubled the output of the Flicky power block and it could milk lots of lines effortlessly. The most notable person attributed to the Bloxeed competition might be the circuit inventor Higashi-rensha-do(ひがし連射道), who was also the coiner of the term "synchronized autofire" and acknowledged by the former record holder RAN at the GAMEST magazine. It is possible to achieve 500 lines in Bloxeed only with non-sync autofire (It was said the player ISP. hit 521 lines without sync autofire) or with only the single sync button autofire (the author managed to score 502 lines this way in March 2020). However, the ultimate speed of rapid-fire seems more effective when a player activates Satellites rather than Flicky because its shots can eliminate most of the stack even if you are on the brink of topping out that is completely overpowered.

We can purchase a variety of circuit boards enabling sync autofire nowadays, but the author is using NRS-1 autofire PCB produced by Nautilus, Ltd. and recommends it because it is easy to use without the knowledge of soldering and circuit construction. Here is the introduction to how to configure the NRS-1 board setting that suits to play Bloxeed. If you can read Japanese, the online manual of NRS-1 is available(

Having two single-fire buttons besides regular/inverted autofire buttons makes the rotation very comfortable at Level 50 and over. (To execute 270-degree spin, input the button ABA quickly.) It is possible thanks to that NRS-1 can assign a button to different button input(s). Of course, setting C inverted and D regular is okay, or you can assign A and C for single fire and B and D for autofire (when you want to avoid confusion with other Tetris variants in which button B rotation is opposite to buttons A&C.)

How to configure NRS-1

[*1] (ま) was printed as a circled hiragana "ma".
[*2] Bloxeed only has three buttons, so a button assigned to D (as well as button E or F) results in disabling it. That is why you must switch the output of button D to either A, B, or C.
