Cute intuitive game. Although the matching bonus is easy to guess, the extra card at 10 is harder to guess. Sometimes a complaint is that you might add 3 or 4 to 8 and expect to be left with 9 points (8+3-2) or get 2 extra cards (8+4-2-2), but I don't think it worked out that way. Despite this, trying to get extra cards is often worthwhile, since they are worth 2+, so you sometimes even forgo a matching bonus (+1). I managed 106
