To consistently get a Match at the end of a game, time your button press to when the value you need to hit is 30 more than the current spinning value. For example, if the number to Match is 80, stop it when you see 50. This does take some practice to get the timing down, as it may vary slightly from table to table. Each time you make a Match, you earn 1 credit, so once you have the timing down this is an easy way to regain used credits or earn credits faster on Free Play tables and modes.
Instead of tapping the button hold it down and release it when your ready. You should be able to get it almost every time!
To unlock the Unlockable Options for a table, which allow you to choose a Custom Ball design, allow Tilt, and play in Mirror Mode, complete all Table Goals and then complete all Wizard Table Goals for that table.
To unlock a table's wizard goals, complete all 5 of a table's standard goals. This also allows you to unlock one table's Free Play mode without having to pay the normal fee of 100 credits. This can be done in both Free Play and Williams Challenge modes.
