DUNE: Keep the Secret (Longplay) - Level 4 of 5
Level #4: On this level you need to find the final scarab in the game. The puzzle of this level is a classical «jars and water» thing. LEFT jar can accommodate 3 liters of water. The goal is to fill the RIGHT jar with exactly 4 liters of water and put it on the right scale pan. The RIGHT one -- five liters. Here's how you solve the puzzle:
1. Fill the LEFT jar (take the LEFT jar and click on the pool of water).
2. Put 3 liters of water from LEFT jar to the RIGHT jar (click the LEFT jar on the RIGHT jar).
3. Fill the LEFT jar again (click the LEFT jar on the pool of water).
4. Put two more liters of water from the LEFT jar to the RIGHT jar (click the LEFT jar on the RIGHT jar). Now the RIGHT jar is full (5 liters) and there's 1 liter left in the LEFT jar.
5. Empty the RIGHT jar (take the RIGHT jar and click it on the pool of water).
6. Put 1 liter that left in the LEFT jar to the RIGHT one (take a LEFT jar and click it on the RIGHT jar).
7. Fill the LEFT jar again (click the LEFT jar on the pool of water).
8. Put 3 liters from LEFT jar to the RIGHT jar (click the LEFT jar on the RIGHT jar).
9. Now you have exact 4 liters in the RIGHT jar, so, you can put it on the right scale pan to solve the puzzle. Do so to get your final gold scarab.
There are two final artifacts on this level and only one exit.
