In serpent temple there is several locked doors with skull levers and coin slot.
What is the combination of skull levers that open doors ?
And should I use coins in coin slot ?
Please help! I've tried allmost all combinations...

Ok. I get all but one door open.
It seems to be stuck.

Levers from left to right.
Doors from left (1) to right (6)

Door 1: up, up, down, up
Door 2: up, down, down, up
Door 3: up, up, down, down
Door 4: down, down, down, up
Door 5: down, up, down, down
Door 6: down, down, up, down

Be ready for the released spiders and monkeys!
