Alice and Bob wanted to play a game of Chain Reaction. However, they had a lot of homework to do and had very little time, so they wanted the game to end very quickly.
What is the minimum number of moves they could have made in a single game?
- A move is defined as placing an orb in the grid. As an explicit example, if Alice places an orb, and then Bob places an orb, then they have played two moves. The final orb which is placed, due to which one player wins is also to be counted.
