Goal: score as many points as you can in 90 seconds. Swapping: drag a gem onto a neighbour, or tap one gem then tap an adjacent one.
Match 3 or more of a kind in a row or column and they clear — gems above fall down
and new ones drop in. Scoring: each cleared gem is 20 points, multiplied by the cascade level:
the first clear is ×1, a chain from the falling gems is ×2, then ×3, and so on. A plain
3-match is 60 points; a long chain is worth much more. No moves: if the board ever has no move that makes a match, it shuffles itself
and play carries on. Hint: shows a swap you can make. Posting: finish a round with 1000 or more and you can post your score.
