Lightning puzzle?

[The Old Taylor Swiftsz]

How do I solve the puzzle with the yellow lightning tiles? Only one tile is unlit and stepping on it turns one of the tiles beside it off, and after about 2 or 3 cycles, I just get a sweet apple cause all of the tiles are lit. I assume I'm supposed to turn them all off? There's a panel of 5 blue tiles beside the lightning tiles themselves but none of them light up so I'm also not sure what those are for. Just the whole thing is odd to me. I'm sure there's better loot you can get but I haven't myself been able to figure out how the puzzle works. Does anyone know how it works?

A friend and i just figured this one out today. It's a speed puzzle.

Step on the unlit squares as rapidly as you can. Just keep stepping on the unlit tiles, over and over, as they appear. The more you do, the better of a prize you get.

Our first try after 'figuring it out', we got a silver chest reward, with 4 lights lit up. Next time, hopefully, we'll be prepared and get a GOLD chest (which we don't even buy keys for, lol)!

Well that explains a lot. I'm slow as molasses during the puzzle cause I'm trying to figure out what to do haha. Thanks for the quick insight!
