The only Othello app you will ever need!!!

The developer of this Othello app has a Doctorate from the best PhD program in mathematics in Europe (ENS Ulm) and it clearly shows. The AI is just superb. It is a pleasure to play at level 1 for beginners (yes, you can win at this level) and you still have 9 more levels to explore. The latest and highest level will be challenging even for Othello champions. It's totally free (but you can contribute by buying goodies if you feel like acknowledging the amazing programming and AI behind this cute game). In short, truly challenging, free, no ads, with 10 levels of difficulty, and you can play with your friends too.

Great app. No ads, no tracking, a pleasure to play. One problem though: the sound is either on or off. Trying to make the “clicks” more quiet using my iPad +/- buttons does nothing. If the sound is on, the iPad will play them even if the volume is all the way down.

UPDATE: The sound problem is fixed. This is now a 5-star app, easily the best Othello in the app store.

Developer Response ,

Dear FractalShade,

Thank you for your review. The issue you're describing has been fixed in the version 2.12 update, which should be released soon. Should you find the fix satisfactory, we would very much appreciate it if you could then update your review! :-)

Thank you for playing!

Fun and Well Designed...One Minor Issue

Really fun for casual play across devices. Overall, simple and elegant interface – easy to get started.

One minor issue. When a game is complete and a winner is declared, have the dialog box identify a winner and ask to play again. Instead, it asks if you want to "abandon the game."

Developer Response ,

Thank you very much for your wonderful review.

The reason why the software doesn’t immediately prompt you for a new game, and the reason why it asks you to confirm if you want to “abandon” an otherwise completed game, is the following:

When a game ends, a player may want to undo a number of moves and to try different strategies or to otherwise study the game. Not requesting that the player confirms abandoning a game could inadvertently cause them to start a new game when in reality they wished to undo a move in the current, finished game. As such, the current dynamic will not change.

Regarding the identifying of the winner: it is easy to identify the winner simply by looking at the scoreboard at the top of the screen.
