I was playing a 24 hour, most spins tournament, warlords a couple years ago. Balance stayed steady until the 23rd hour and I was comfortably ahead with a couple people chasing me, all looking good for £1500 prize.
Then, disaster, I hit the blue bonus.... stupid thing kept retriggering, 200+ spins - paid next to nothing and as it was a bonus round all the free spins combined counted as 1 spin. Sat there begging it not to retrigger, collecting the pittance wins, watching player after player overtake me on the leaderboard.
Ended up 6th for £75 prize. 24 hours wasted - well, not really wasted as I enjoy such things, never mind.
