A relatively simple explanation is that the first requirement of "getting" a wicket, assuming the game is in play, is for the bowler to bowl....... care must be taken that he does not bowl a no ball. The bowlers options include spinning which may include a leg break, a googgly, a chinaman, an off break or even a wrong un .... alternatively they may decided to swing the ball, pitch it short or up, though a full toss is usually a bad option, but, a bouncer can be effective ..... though the bowler has other options i will not list them in fear that it might confuse you
.
After the bowler has bowled, unless he hits the stumps or the batsmens leg before (this requires agreement of the umpire to ensure that the ball bowled has met a list of criteria which if listed may lead to a small amount of confusion), assistance is required from other team members to either catch the ball (before it has touched the ground) ... (some have been known to use parts of their body or even clothing pockets to prevent the ball bouncing), or run out one or both of the batsmen who are at the crease ..... unless of course the bowler had caught and bowled the batsman.
I am sure that this simplified explanation will, as Petra has just said "enlighten" you and help convert you into an avid follower of this most interesting and thrilling of games. Should you require any further or more detailed explanation to help you enjoy this spectacular game do not hesitate to ask
Mim has access too, just in case she runs out of stuff
