Safari has a unique 'tower game' on the right hand side of the backglass: the Animal Feature.
You coin this up with the white button, and the idea is that several holes on the playfield will move you up or down. Ideally you move either all the way up or all the way down.
This will light the giraffe, which gives you your best payout!
The same Mystic Lines gameplay from London returns, including the Twin Number feature.
