Arbitrage in accumulator

[gamdom]

I have offer in accumulator bet . 8 event that single odds is 1.8 in each event, normal accumulator odds is 1.8*1.8*1.8*1.8*1.8*1.8*1.8*1.8=110
But my offer odds is 250
All games is soccer (1x2)and start in same time
How can i create arbitrage profit in this offer?

How do you find 8 games at 1.8 starting at the same time?
Consider you will only get 1.994 in each game. It's not a huge change individually.
