My top 3 "value for money" sited pins to play in Melbourne are;
1.CFTBL - High St, Thornbury = $2 will give you 3credits, an achievable replay target of 134k and has NEVER failed on me once (ie - lost balls, level playfield, etc..).
2.SS - Edward St, Reservoir - Great machine, although you only get 2credits per $2 coin. 30k replay is quite challenging.
3.TOTAN - Lygon St, East Brunswick - This machine was the best one in Melbourne, prior to its current location now. Its flippers have been tweaked and the ball tends to bounce alot. The playfield leans to the left and I’ve had a couple of balls stuck (once behind the genie).
Other than that, 3credits per $2 coin.
Forget going to the Airport. Coin mechs are rooted on some machines (TZ) and you only get one credit per $2 coin. TOM is probably the best one there, though the security guards/airline personal will question you, once you pass through the scanner, heading towards a gate with no plane!!
Just smile and say "I’m here to play pinball"
Don't forget your car park bill to consider = expensive.
The Cue in Fitzroy = too dark in that joint and music can be of bother when it's loud.
Where are you based in Melbourne??
Would you like to play a CV in Werribee??
What about FT in Fitzroy?
