Ten Aliens Find Themselves At The River

How the aliens communicate is beyond me. You gotta help them though. They’re stuck.

There is a river and ten aliens on the south bank. Aliens cannot swim, but they can teleport. Teleportation uses energy that is common to all ten aliens. Your goal is to transfer all aliens to the north bank using no more energy than indicated in the upper left corner of the module. Each alien has one or two RGB-components (red, green, blue), and may mix together.

There is a reset button on top of the module. Hold it for one second to rewind back to the initial state if the current state isn’t. This action will give you a strike.

Teleporting an alien by themselves cost 8 energy. This can be done by holding a single alien at the bottom while none of the upper aliens are selected.

To teleport an alien with another alien, select the alien to use on the top of the bank and then the alien you want to teleport with at the bottom of the bank. You can also hold the alien you want to teleport with to teleport all of the aliens with the same color.

In each table provided, the first cell denotes the color of the alien; the second denotes the energy cost to teleport other aliens; and any further cells denote what colors the other aliens must be to teleport them. Note that if the color from the table provided is absent, you should NOT teleport the alien of that color using the selected alien. Doing so will result in a strike.

When the module is solved, you can hold down restart to generate a new puzzle. The solved module will no longer give you a strike. This is a great opportunity to practice soloing this module while the expert is messing around solving other modules.

The next page will contain the solving procedure.

Solving Procedure Layout

Base Procedure:

Using a colored alien means using an alien that has been teleported to the other side of the river.

1. Teleport 1 yellow alien alone.
2. Use the yellow alien to teleport all blue aliens.
3. Use the blue alien to teleport all yellow aliens.
4. Teleport 1 magenta alien alone.
5. Use the magenta aliens to teleport all green aliens.
6. Use the green alien to teleport all magenta aliens.
7. Use the green alien to teleport one red alien.
8. Use the red alien to teleport all cyan aliens.
9. Use the cyan alien to teleport all red aliens.

In a case where a colored alien is missing, do the base procedure but with the notes on each bullet for each missing color in no particular order:

• No green: Use the blue alien instead to teleport a red alien. If there are any magenta aliens, teleport them by themselves.
• No blue: If there are any yellow aliens, teleport them by themselves.
• No red: If there are any cyan aliens, teleport them by themselves.
• No yellow: Use the red aliens to teleport the blue aliens instead.
• No magenta: Use the blue alien instead to teleport a red alien. Then use the red alien to teleport all green aliens.
• No cyan: Use the green alien to teleport all red aliens instead.
• A combination of those: Teleport the alien that can teleport others at the lowest cost. Then combine the modifications based on the missing colors.
• Exactly 3 colors missing, leaving 3 that share 1 RGB component (I.E only red, magenta, yellow aliens; only green cyan, yellow aliens; only blue, magenta, cyan aliens): Teleport ALL of the aliens by themselves.
