http://pachibee.7world.jp/movies/index/5561This is titled as Alucard Mission
There are 2 versions for winning. The first one shown is where you get lucky with the slots.
Script: (My japanese is somewhat rusty right now, but i'll try my best to translate. Note I did not translate the blue text that hovers in front of the machine, these are hints to those who would play the machine, like what to expect or do when this screen or title plays, or just to note that this is quite different from something you saw before, etc.)
Alucard: Let us begin
Trevor: "something" battle (trevor mumbles this so I can't get what he is saying, plus the kanjis are small)
edit:thinking about it again, he could possibly have said "let's duel" slot machine sound
Alucard : That's a pretty good arm
animation plays, Alucard falls on his knees
Alucard: Is this the power of humans?
You win
The second version shows if you do not get lucky, then Alucard can counter your whip, but the game gives you a second chance, spin the right slots then trevor will say "do you think I plan to lose?" and you win.
Script:Alucard: Let us begin
Trevor: "something" battle
slot machine sound
Trevor: Are you easing up?
animation plays, trevor falls
Alucard: It seems that I have not overestimated your ability
Second chance moment animation plays
Trevor: do you think I plan to lose?
Animation... there's a part where the whip grabs Alucard's sword, Al says "what?"
YOU WIN.
