36 Roulette System
The 36 roulette system covers every single-zero pocket, but seven outcomes still lose money and the expected result remains negative.
A 380-unit fixed layout returns different amounts on zero, the first dozen, a six-line, and high. Coverage is not the same as profit.

Worked example
At 4, the first dozen returns 390 including stake; subtract all 380 units wagered to get +10. At 15, the six-line returns 180 including stake against the same 380 total: −200.

Cost and risk
The layout’s expectation is (−20 + 12 × 10 + 6 × −200 + 18 × 40) / 37 = −380/37 units. The claim that it makes money on every number is contradicted by the placement arithmetic.

Questions
A winning bet’s gross return can be smaller than the entire amount initially staked. Zero is covered here but nets −20.
The stated layout needs a separate 38-pocket calculation; its single-zero claim cannot simply be carried over.
