Ever seen this mistake in Sonic 2? #retrogaming #sega #sonic2

In this video I demonstrate the weird glitch I found in the original Sonic The Hedgehog 2. It's present in the Mega Drive original version and on the Sega Mega Drive Mini, but not in the iOS version by Christian Whitehead. The second line comprising three rings to the left of the restart post are worth two rings each. Any idea why?

Probably just rings stacked on top of each other. Happens in a lot of other places too.

Rings got stacked into each other. I recall it does happen in other levels but never documented.
A similar mistake can be seen in Sonic 3 (without the & Knuckles lock-on) in Hydrocity act 2 where after a loop sending you in a ramp underwater, if you miss, you’ll find a hidden wall with a ring box inside. Totally normal, however, it will give you 20 rings instead of 10. Same issue.

I remember literally screaming at the death egg robot and silver sonic, I DIDN'T HAVE RINGS.

A slight oversight, that's all. Probably people can dissect the rings and find there's 1 stacked up on each other.

I can see by going frame by frame that out of the rings you collected, the first one gave 2 rings, the 2nd gave 1, the 3rd gave 2, the 4th gave 1, the 5th gave 2, and the 6th gave 1. if you add this all up it's 47+2+1+2+1+2+1=56. I don't know why this happened, or why every other ring is doubled, but i'm assuming that there is a 1.5x ring multiplier of sorts, and the number displayed on screen is rounding up while the actual value is going up by 1.5 instead of 1.

[z.a.k.e.n.]

video games from the 90s being weird.
and I can see you're using the original megadrive version; that's prone to happening.

You collected to 56 in that jump and slow down and then hit the checkpoint
There's no mistake here
