There's no precise walkthrough for this game. The door you need is randomized every time. As to which door? The angel/devil can provide a hint. You may notice something about the three numbers they have. The fractions are also a clue.

If you need practice with the general concept, you can wait twice and go to the side room, which has 30 doors. So after about seven tries, you may be able to sort what a finger does, or what heads/tails or rock/scissors/paper do.

If you chart out what goes where, you may find each attribute of the lonely statue has different values. The fingers are probably the easiest. With heads/tails and rock/scissors/paper constant, you'll note the differences are multiples of 6.

thumb=6 index=12 middle=18 ring=24 pinky=0

rock=10 scissors=20 paper=0

heads=15 tails=0

Add these up and modulo 30 and there is your answer.

The door in the other room has 7, 11 and 13 different possibilities, and 7*11*13=1001. Take away door 1001, and you have 1000 possibilities. The numbers are sticky here, but you can also extrapolate from the easy room.

The notes are potentially easiest once we know what to do.

A=143
B=286
C=429
D=572
E=715
F=858
G=0/1001

Saggitarius=77

Aries=385
Taurus=462
Gemini=539
Cancer=616
Leo=693
Virgo=770
Libra=847
Scorpio=924
Ophiuchus=0/1001 (yes, it's a new Zodiac, potentially apocryphal.)

Goalie=91
Right Full Back=182
Left Full Back=273
Right Half Back=364
Center Back=455
Left Half Back=546
Right Winger=637
Inside Right Midfielder=728
Center Forward=819
Inside Left Midfielder=910
Left Winger=0/1001

Add up, modulo 1001, and you're done.
