I have worked out that as Spider starts with a score of 500 points, then adds 100 points for every full suite you successfully remove (=500 + 8 x 100 = 1300) and then deducts one point for every move or undo you make. So to get a score of 1292 you would
have to have cleared the whole board in 8 moves, which is obviously impossible!
I have collected enough info to fix this and sent it to Microsoft ages ago. I guess it got lost somewhere though, so here it is:
There is a bug with scoring. When you reach a dead end (game end) with a move that clears one suit (one pack of the cards? and have no moves left, game over), and you press "cancel" (undo last move), it performs "undo" for last 2 moves instead (the one that
completed the suit and previous one). At the same time, score for removing the suit (+100 points) is
not removed.
Because of this bug, under certain conditions you can have infinitely high score (tested, you can simply complete a set and get "game over" error, undo and repeat infinitely and the score gets higher, I reached 5k points before I got bored).
