Quoted from Jethrodog:
I just noticed that if I max out the bonus multiplier at 10x, but then collect the bonus at the lower kicker, then the bonus awarded upon draining is awarded at 5x even though the 10x light is lit before the drain. If I drain without collecting up above, it awards the 10x normally. Is this normal? Anybody else have this issue? Nothing obviously fried. Seems like it could be in the programming, I can't find anything else wrong.
The game is designed to take away the 10x if you collect it midfield. If you complete the 5 bank again after doing so, it should relight for 10x and collect 10x the next time. The only bug would be why did the 10x light not go off?
I can tell you for sure that if the game has the 10x lamp lit, that's what it's keying on in the collect bonus routine - there is no separate variable for the bonus multiplier, it's the lamps that are lit that control it.
This is any ball that relaunches without scoring - or if your outhole double fires on launch. The background sound start on this game is a toggle - on, off, on, off, on each ball launch. Although, I hadn't ever tried a double, then drain to see if it starts again. It might not.
Regardless of how it works, there is a fix for it on ipdb as L3.
