How to design betting game using sum of two dice where the expected value of a single play is $0.18 in favor of the player? i was thinking: if you roll the sum divisible by 3, you will get $2.54,otherwise,you loose $1?

$\dfrac{2}{6} * 2.54 + \dfrac{4}{6} * (\ 1) = \dfrac{5.08  4}{6} = \dfrac{1.08}{6} = 0.18.$ Your answer looks good to me.
