Here are some Tips and Tricks you can use to become better at Worms:

• You can use the laser sight to try to hit long distance shots, but using the rope to aim, you can get an even closer.
• If you use invisibility with teleport, you can sneak up on an enemy without them noticing.
• If you name all of your worms the same, your opponents won't know which one of your worms is going next. 
• When using sheep, remember that they can also collect weapon crates if they come across them.
• You can take the baseball bat and hit land mines to move them closer to your enemy.
• When using dynamite, try to put it somewhere where there are more than one work no make the damage more amusing.
• Watch the sequence of worms playing, so that you know which worm is going next.
• It is always a good idea to dig one or two worms deep into the ground...they can't be hit, and can use air attacks to still be effective.
• Try to remember what weapon your enemy has used.  This will allow you to know whether or not you can try certain moves.
• If you use Low Gravity and the Baseball bat, the impact will be a lot greater, because the worm will fly longer and higher.
• The Homing Missile can be used as a torpedo.  Shoot it low into the water and it still can hit targets that are positioned very low and can only be reached through the water.
• Make sure that you know everything about the scheme that you are playing with.  This allows you to know what you can and cannot do.
• Remember that you can use weapons while suspended from a rope or going down with a parachute...you only have a few seconds after that to get somewhere safe though.
• When the enemy is close to the edge, put a mine on the opposite side to blow him right off the edge into the water.
