Circle game can be easy:
• Find how to solve one position. Remember it.
If you see it — Solve it.
If you don't see it — Bring random position to the one that you can solve.
For example, I can solve one dot. So, I bring other position to one-dot-position and solve it.
• Remember more recognizable positions and solutions to them.
For example, cross-position or three-in-the-row-position are easy to solve.
• If circle is the first game you can reroll it to easy position or even one click-to-win-position.
