Binary #603 is a 6×6 grid at easy level. 11 of its 36 cells are given, about 31 %, and the other 25 follow from the three rules.

The givens already show 4 pairs of equal symbols side by side. Close each pair with the opposite symbol at both ends: that is the quickest start.

There is one gap between two equal givens. Each takes the opposite symbol.

2 lines already hold half of one symbol and can be filled with the other straight away.

On an easy grid, pairs, gaps and counting carry you to the end.
