Mastered! I never want to see a blue sphere again!!!
Nabas6545 16 May 2024 07:35
After having not played blue spheres for a while, it took me a few goes to get back into the groove of it. The achievement badges look great, looks like a lot of thought and care went into creating them.

Given how tricky some of the levels are, I made a video showing perfect clears for all the individual level achievements. Hopefully it might help someone else master this set by seeing what routes I took. You can find it at https://youtu.be/gkkA0yQ3gc0

Mastery #16! I'm going to admit, had the codes not been provided I would have never done this. Never did dive into this game that deeply as a kid. However, this set changed that. Thank you RetroSprites!

How to even play?

I am the blue spheres guy.

Well, this is my first game ever mastered. supposedly it took me "6 hours" but it felt much shorter than just that, I really enjoyed this game, and I would reccomend this for anyone that wants to master a semi-easy game at best. (also am I the only person that used https://bsgen-new.neocities.org/ and not https://bsgen-old.neocities.org/ for finding level codes) Well it seems like it's over, goodbye Blue Sphere.

Mastered #9! Blue Balls
Capeira 14 Jul 2024 19:00
a bit hard but still fun.
I always loved these special stages from S3K because they require skill and are about reaction times, its good.
Also in Origins they changed ''Blue Spheres'' to ''Blue Balls'' and apparently that change also appeared on other languages for that game.
god im tired of catching these blue balls man

That's weird, I thought I remembered there being an achievement for the special stage you get from attaching Aladdin, but it's not in the set, nor does it appear when "Test Unoffical Achievements" is enabled. Am I remembering this wrong or was the achievement repurposed?
turtlebearman 11 Dec 2024 03:12
9th master for me! I had a ton of fun learning all the stages. You really start to see the patterns and tricks they like to put in the harder stages after a while. This was a great sampler pack of a set. Thanks for this one!

The first 678,923 stages are all time classics.
dominguito 21 Jan 2025 18:16
What is this?? why are the achievements so weird?
starlite 2 Feb 2025 19:45
@dominguito The first 13 achievements are for one stage with each level of difficulty.
- Stages 1, 11, 21, and 31 have difficulty 5/7/8/10, and are the first four stages you play in order. So they all get achievements.
- The next stage you would play, stage 41, is difficulty 8 again, so the pattern changes: The next achievements use the round number stages 100; 1000; 10,000; 30,000. These stages have difficulty 6/12/11/9.
- Then since the remaining difficulties (1, 2, 3, 4, 13) don't appear on any nice round number stages, the stage used for the remaining difficulty achievements are just arbitrarily chosen. Stages 81,193,028l 113,406,233; 9089; 54,479,233; 23,411,487 have difficulty 1/2/3/4/13.

I think the reason stage 123,456,804 has an achievement because it was the last stage listed on a bunch of level code lists online. Apparently there are actually 128,016,000 unique stage layouts in the game and it will count up to stage 134,217,728. But these stages aren't listed on the common level code lists online, so 123,456,804 gets the "Final Blue Sphere Level" achievement instead.

The other achievements are all self-explanatory from their description - beating stages special numbers, beating a stage that appears in Sonic Mania, beating the stage you get for linking S+K with Sonic Spinball, and beating the first 14 stages in one sitting.

Mastered! A very fun and challenging set. One of the best sets I've played on this site.
WikistudioS4TURN 8 Mar 2025 19:40
A very fun fact is when you press A, B and C at the same time before "No Way" screen will appear the characters will be glitched. It's a fun little easter egg.
