This one really works your math skills; I had to do some algebra to figure out the break in. Quite nice.

This was far harder than expected, especially that one step in the middle, which was very satisfying to find. Thanks for the challenge.

Very nice! I got completely stuck in the middle and it took me ages to find a way to proceed, but the revelation I got was completely worth it. Thank you

Same here, completely stuck after a smooth break in. You know where the pressure is, but still hard to make some sound deductions. 4 stars for me.
