Sorted - I'll fiddle it using the roulette wheel.

Bet £5 on black, £5 on red and £1 on green and then spin a few times to rack up the £400

You'll not loose much but you'll gain more than the £10 if you have won on slots etc

I got lucky and dropped green Zero twice along the way LOL


Or does the roulette wheel not count towards the total of £400 wager?
