Game Amount total - question

I have 705 games in stats and in admin it says i have 730ish
i have deleted games from the database before is the amount on stats wrong? or it the amount of the admin cp wrong? when i view the pages the last number is the 730ish in stats box its like 705

game ID is not its serial number, field ID in the database is autoincrement, so the game with id=730 don't have to be 730th
