INSIDE TARGET THE LINE
Every line is a new challenge.
THE CORE LOOP
Easy to learn. Hard to master.
Complete lines that meet the TARGET: sums, number pairs, values to include or avoid, and end cells. Correct lines charge your energy; incorrect lines stay frozen and apply a penalty.
For example, if the TARGET requires a sum of 18, a line containing 4, 7, 2 and 5 reaches the required total. When the TARGET changes, the combination you need changes too: always check the rule before completing a line.

Calculate
Read the TARGET before completing a line: the condition changes from one level to the next.
