Far from the original The most challenging part of the originally game was to add the numbers up to 0 (MOD 10) to get at the n. And one has to cycle through 11 digits. (yes, 0 WAS there to make the mental count more difficult) Without the "addition" bonus, this game has degenerated into a boring "shot 'em up" type of game. Version 2 in the works?
Great effort but wrong logic. As stated by others, ufo appears whenever the shot down aliens sums up to 10. 5* otherwise.
It's not same as the original. Have u played the original? The alien should come out when sum up to multiple of ten. And no 0 at all.
Like it I did have one of those calculators that had this on reminds me of those days not strictly like the original but fun to play
Very uninteresting. Gets boring too quickly. HTC Hero
Bring back memories Need to fix the ufos. They should turn up when you add up to a multiple of 10.
