Bubble 4+

This game is highly addictive and quite satisfying. However, I very much agree with the person who said it would be improved by it telling you the maximum possible score for each board and allowing you to try again with different strategies. In the same way, it would be interesting to have more than one level of undo available and that would be one way to achieve the ‘try again’ outcome, although it wouldn’t help you to know what the maximum possible might be. That (theoretical maximum) might be very hard to program, however.

Superficially simple but challenging as you start to think strategically and Very Addictive. Would be improved, I think, if programming gave you the maximum possible score for any given sort and allowed you to replay games to try and improve your strategy. Don't know how complicated that would be to achieve - numbering games would be a start.

Because it keeps score of each game and ongoing averages, there is always something to aim for. I usually try to clear the colour with the highest number. However, sometimes a column will not contain that particular colour, so it is impossible to join them horizontally. A good game to fill in a bit of idle time.
