My best win on John Wayne was in a bonus with a max bet ($3.00) and 50 initial free spins. I won just a tad over $1k. I was disappointed though because based on some of my other bonus rounds, I feel like I should have won considerably more.

For these types of games (spinning streaks) we have the following to choose from around here:

John Wayne
Kingdom of the Titans
Jewels of Africa
The Monkees
Bamboozled

The most initial free spins you can get on John Wayne & Kingdom of the Titans is 50 and it's 40 for the rest of the game.

I've gotten 50 & 40 multiple times on each game, but haven't really had an epic bonus yet. However, they are still my favorite games to play.
