I recently received notification from Apple that Reversi is a trademark of Ravensburger AG and that I needed to change the name of the application, or take it down. I know that Othello is a trademark (of Anjar Co), but thought that Reversi was a generic name and not a trademark. After some investigation, it transpires that Ravensburger AG have a European trademark for the name. Mattel also held a US trademark for the name, but this lapsed in 1989.

I stumbled upon this reversi game, Deep Green Reversi, which runs on Android. The graphics in the game, in particular the status bar under the board and the menus look very similar to Reversi on the iPhone. Furthermore, the game description for Deep Green on the Android market is an almost verbatim copy of the description for Reversi on the App Store, with 'iPhone' replaced by 'Android'.
Much time went into making the AI of reversi strong enough on its higher levels to challenge human players. The highest three levels (of the seven available) are challenging for most human players. On the lower levels, the intention was for it to play as a novice human would play. On the lowest level (beginner) in particular it plays for short-term gains, without considering longer term strategy at all. On each turn, the beginner level plays the move that flips as many of the opponent's pieces, taking a corner if one is available and avoiding squares that would give the opponent a corner on the very next move. This reflects the basic manner in which most novices would tend to play reversi.
It's a departure from my two previous games, Reversi and Merelles, which were both abstract strategy games. Magnetic Block Puzzle is, as the name implies, a puzzle game. The aim of each of the 110 puzzles is to join the coloured blocks, which are special magnets that only stick to other blocks of the same colour, by tilting the puzzle to make the blocks move.
