Beyond the 3rd endless mode

Due to the game.xml Problem, there are no more endless mode loops past the 30,000 distance mark, so there aren't any real endless modes past the third endless mode. After the third endless mode is passed, the Repeating Room Glitch starts, so the game can continue until it breaks or stops, the device's battery runs out, or you run out of balls.

4th loop
The fourth loop occurs between the distances of 36000 and 44000.

MondaysAreTheWorst
MondaysAreTheWorst got a high score of 40543 on January 26, 2020 (in the pacific state time), before it was that high score, he posted a comment on 5th endless mode (at that point he commented he was a anonymous user), saying the score was exactly 36000 points (previously).

"anyone realized that i scored a EXACT 36 THOUSAND [36,000]?"

(However, it was previously 30923 points prior to that comment indicating the high score and prior to the high score of 40543). The high score 40543 was in Mayhem Mode.

A youtube channel called Smash Hit uploaded this Smash Hit video, demonstrating the Repeating Checkpoint Glitch:

A comment on Smash Hit Glitch In A Glitch - The Room of Purgatory (34170 points) said that the score was 41895. It came from a channel called Sushil Palik. (Previously, the score was 37070.)

Sandeep Sharma
A Youtuber named Sandeep Sharma posted a comment on SMASH HIT NEW HIGH SCORE-17,998 that said, "My Score is 45900" It may well be one of the former world records of the game. (comment here) NOTE: There is no other proof, as far as the Smash Hit Wiki community can tell. Not even a video on the channel.

MWFAE924TGWL / Microsoft Windows XP
Another Youtuber named MWFAE924TGWL / Microsoft Windows XP (Andrei Alexandru Cuglea on the Smash Hit Wiki) commented on the video Smash Hit Glitch In A Glitch - The Room of Purgatory (34170 Points) which said "Well, Mine is 47228! HA! TRY TO BEAT THAT!" (comment here) '''(Although that was a reply to a certain youtuber that commented on that video). It may well be another former world record for the game.

NOTE: There's a video of him (MWFAE924TGWL / Microsoft Windows XP) failing at checkpoint 4 with 5 balls (posted only a month after he made the comment), and there is no evidence to prove this is a real score. In the video Alex plays Smash Hit, he is only at 0, and gets to checkpoint 4 with best distance of 4263.

The 6th loop occurs between 52000 and 60000 distance.

"67347 score days in trying to do this"('''comment here) on the video SMASH HIT NEW HIGH SCORE-17,998.

This is a former world record of Smash Hit.

Henzo Uriel replied:

"Try to beat 62225 that's my score and I'm not kidding"

(comment here) on the video Smash Hit Glitch in a Glitch - The Room of Purgatory (34170 points).

This score might have been another former world record of the game, up until MMAADDEEIIRRAA :v beat Henzo Uriel with 67347 (which then was beaten).

8th loop
The 8th loop occurs between 68000 and 76000 distance.

Windows 7 Ultimate
Windows 7 Ultimate replied to Ryan Chan in the video Smash Hit Training Endless Mode GLITCH (random rooms), that a score of 73,561 was attained. (http://youtube.com/watch?v=v87lE3RnYnk&lc=UgylkyjM0KbAYnOIJ7N4AaABAg.8wSpuwh2wBt9G4QxCnD7MX)

"@Ryan Chan I think that makes sense Because in classic I have 73,561 as my high score and it’s mediocre just like 20,000 or whatever above number I was."

9th loop
The 9th endless loop occurs between the distances of 76000 and 84000.

Marina owo
Marina owo beat the record of 67347 at one point, it was a reply for that comment Henzo Uriel posted on that video.

"Well guy gained a 78k [78,000] >> :D."

78000 is another former world record of Smash Hit.

Shovel Knight
Shovel Knight, here FE1GuidePlayz, got 82356, the highest score as of 2021.

Naninalico
In second place, Naninalico got 81208.

Maribeth Luciano
According to this comment, a player called Maribeth Luciano got 90215264 in Mayhem Mode. This was most likely a hack, as only a few months ago, the same player only got 6580 in Classic Mode, and then only a few days before the excessively large score, the score was 26906 in Classic Mode. (This player must have purchased premium then sped up time with a mod/ball-grinded for hours, or hacked the game.)

Playing non-stop
This would take a whopping 118560 seconds (1976 minutes, equivalent to 33 hours or 1 day and 9 hours) to reach if the game were played non-stop, so it is most likely impossible unless you were to stay up all night and through the next day as well.

Playing non-stop would be impossible because the battery would run out, even in an all-day phone unless you charged it all the time.

You would likely get a very high electricity bill, and the ball count would have to be hacked unless you spend an extremely long time ball grinding.)

A technical mod might help. See the Smashing Tech Wiki.

On-off playing (Random Rooms Glitch)
An alternative method would be to waste the day time in the Random Rooms Glitch, then power the phone off all night, resetting the choice of rooms, and setting back distance to the beginning of the last room you were in.

You would still need a lot of ball grinding.

Disclaimer
(If it's not clear, Don't try those both ways at home!)

Since 999999 is the max distance, that is the maximum distance meaning that this is the maximum possible world record of Smash Hit.
