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
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
- 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.
The Blue Sphere Nightmare is just the beginning 🔵
