yes i totally got that when i played the extra content and lost with all the after take. I support your take on gambling. For a video game, i think it should remain engaging somehow.
If you add anything that indicate that your win had somekind of change in the situation (even a change of the colors light that do absolutly nothing else would work, the player would go hum the light color has change when i won so maybe if i win again something else will happened etc... leading you to a certain defeat), that would totaly work for me i think :)
