For those people saying the game is too complicated to understand the rules.
Here is how I 'attack' a game I've never seen/played before.
1: First few games just hit shots to see where the ball returns.
2: Figure out how to start a mode/feature
3 :Figure out how to start a MB
4: See if stacking is possible with either mode or multiple MBs
Don't worry about the nuances and score too much.
5: Go away and read any rulesheets/tutorials. This can only really be done after you have played the machine so that you can put these things into context.
Go back and play the machine trying to implement whatever you have read.
In all games I can think of that has got me to the point of being able to confidently approach the game in comp or for getting to wizard mode (or at least heading in the right direction)
The same applies here for AV:IQ
After 1: I knew where the ball would return after every made shot. There are no diverters to change the course of the ball if you are in a certain game state.
After 2: Didn't take long to work out spinning disc started a quest, combos lit portal, or how to light each Avenger.
After 3: Easy to figure out Thor, took a little longer to figure out how to change inserts to spell I-R-O-N.
After 4: I knew you could stack a single MB into a mode/quest, but not the other way round.
After 5: I went back to play on site and knew what the gems did, along with the computer/drop grid, and tried to implement that into my play.
Maybe I was focussing on trying to be too clever with gem placement, quest choosing, etc. but didn't get anywhere near the scores I had previously.
TL:DR Just play the game, you'll pick up the rules and nuances as you play. The best score I achieved was just shy of 400mil - on the 2nd game I ever played on it.
