Hyperjumps Explore exoplanets in an 8-planet solar system

Using the planet numbers shown, your mission is to complete:

• four 5-planet sequences
• three 6-planet sequences
• two 7-planet sequences
• one 8-planet sequence

Let’s make a 6-planet sequence.

Your sequence can start at the left with any two planet numbers. Let’s start with 7 and 7 (more than one planet can have the same number).

The next number must be the ones digit of the answer to one simple operation (+, −, ÷, ×) going left to right. If needed, we can combine previous planet numbers into a multi-digit number to subtract or divide the rightmost digit.

Third-planet options:

• 7 + 7 = 14
• 7 ÷ 7 = 1
• 7 × 7 = 49

Only the last planet (Earth) can be 9, so the third planet could be 4 or 1. Let’s enter 1.

Fourth-planet options:

• 7 – 1 = 6
• 7 × 1 = 7
• 7 + 1 = 8

Let’s enter 8.

Fifth-planet options:

• 1 × 8 = 8
• 1 + 8 = 9
• 71 – 8 = 63

8 and 9 aren’t options, and we can’t do 1 − 7 (no negatives). But we can combine 7 and 1 to make 71 − 8 = 63.

Sixth-planet options:

• 8 – 3 = 5
• 8 + 3 = 11
• 8 × 3 = 24

There’s no 5 in the solar system and we’ve already used planet 1. And neither 5 nor 1 works with the 9 at the end. But 4 works, since 83 – 4 = 79.

Press LAUNCH to test your sequence. Congratulations! You’ve completed one hyperjumps trip.

The sixth planet could also have been 6, since 18 ÷ 3 = 6 and 3 + 6 = 9. Enter the new sequence and press LAUNCH.

While math operations must work left to right, you can input numbers in any order.
