I think we should have a solve 70 puzzles because the distance from 50 puzzle to 100 puzzle is very far.

We have solve 50 puzzle and solve 100 puzzle. But solve 100 puzzle is impossible. If play a puzzle rush, we must need a stockfish bot to solve 100 puzzle.

Solve 70 puzzle isn't very impossible, it needs time to find the best move. But it doesn't very impossible because I can do this.
