Konami has taken a few stabs at a game with a hold and respin mechanic; one of my favorites is the Money Galaxy series of games, but as I have had a chance to play them more I am also warming up to the Thunder Arrow series.
My most recent experience was on God of the East, which I am writing about today, but there are a few different versions with minor differences, similar to how Konami handled the Money Galaxy games.
The Thunder Arrow feature is triggered the same way on all of them – get six or more arrows and you enter the hold and respin feature. However, one big difference between this and most link style games is you do not actually get anything for triggering the bonus.
Instead, you enter a series of spins that, like games such as Zeus/Kronos Unleashed, keep spinning until you get three spins with no symbols landed, or completely fill the screen with numbers. Each spin you can land credits or progressives, with your odds of landing a progressive improving with your bet level.
Konami likes creating games with potential, so if you fill the screen, you retrigger the Thunder Arrow bonus, getting the chance to fill the screen with even more prizes. This creates a bonus with more potential, although the chances of moving on to another screen are not huge.
Three bonus symbols will land you a free spins bonus; you get five free spins with additional arrows and wilds added to the reels, designed to amp up the bonus and not unlike Money Galaxy as well. It is possible to trigger the Thunder Arrow bonus multiple times inside the bonus, racking up the prizes and building to a big bonus.
As you can see above, I got a roughly 180x bonus on a 50 cent bet on it, so the potential is definitely there.
