Bowling Terminology

Back Bowl: A bowl that comes to rest beyond the Jack.
Backhand Draw: When the bowl is aimed to the left of the Jack, and curves to the right (for left handed bowlers)
Bank: A defined area beyond the ditch is called the bank. The face of the bank rises higher than the level of the green and facilitates markers that indicate the centre and side lines of each rink.

Be Up: Instruction from Skip to bowl longer (don't be short of Jack).
Bias: Weighted offset to make the bowl curve. The bias side of the bowl is noted by the smaller button. Bias is correct when the bowl curves towards the Jack.
Blocker: A bowl that blocks someone (usually an opponent) from reaching the desired target.
Bowls: Bowls are available in a choice of sizes and weights. Refer Bowls Size & Weight Chart.
The interesting feature about bowls is that they are not exactly symmetrical — one side is more rounded than the other, causing the bowl to curve to one side as it slows down. This is referred to as the "bias" of the bowl. The object is to deliver the bowl as close to the jack as possible. Therefore, if you aim directly at the jack the bowl will curve out to the side.To allow for the curve, the bowl must be delivered to the outside so it curves in and approaches the jack from either the left or the right. The bowler decides if a right or left approach is more desirable.
Note: Each bowl has an engraved circle on each side of the bowl. (one side has a large circle and the other a small circle).The bowl will curve towards the side which has the small engraved circle, so when delivering your bowl, keep the side with the small circle on the inside.

Dead End / Burned End: When the Jack has been knocked out of bounds. The end is not counted and is played again.

Ditches: A rink is terminated at each end by a ditch. The front ditch is at the far end, and the rear ditch is behind the mat. Both ditches are within the boundaries of the rink. A bowl falling into the front ditch is considered "dead" unless it first touches the jack before falling into the ditch — in which case it's called a "toucher" and remains in play.
Draw Shot: Shots where the bowl is rolled to a specific location without causing too much disturbance of bowls already at the Head. (See Hand).

Drive: This involves bowling with considerable force with the aim of knocking either the Jack or a specific bowl(s) out of play.
Dead Bowl: When a bowl either goes in the ditch or rests outside the rink field of play (Lane).
Down: When your team does not have the Shot Bowl, you are considered to be Down. You may be down by one or more points.
End: Means playing of the Jack and all bowls of both opponents in the same direction on a Rink. Bowling to the Jack is called "one end." The number of Ends played is decided by Club Rules. A typical game has 14 ends in social games, 18 in tournaments.
Foot Fault: A foot fault occurs when the bowler does not have one foot over the mat on release of the bowl. Foot may be on the mat or in the air.
Forehand Draw: When the bowl is aimed to the right of the Jack, and curves to the left (for right-handed bowlers).
Grass: Apart from the surface, the directional line the bowl takes in order for it to curve towards the Jack. So a "too much grass" bowl will be wide.
Green: The green is the rectangular playing surface bounded by a ditch and divided into playing areas called rinks, with directions being alternated to protect the grass.
The Hammer: The final bowl of the end. Newer rules allow the winning team on an end to give away the mat and so retain control of the hammer.
Hand: The side on which the bowl is delivered: either Forehand or Backhand.
Head: Rolling bowls toward Jack to build up a Head, which means such bowls that have come to rest within the boundary of the Rink and have not been declared dead.
Hog Line: Special markers (often flags for tournaments) that dictate the minimum line beyond which the jack must be rolled for the end to be valid.
Holding Shot: Team with their bowl(s) closest to Jack (see also Shot Bowl).
Hook: Shape to the end some bowls take, especially older Classic bowls with extreme bias.
cJack: White ball or "kitty" is delivered first, to establish the play to, which determines point scoring (see Points). A coin is flipped to determine which player/team delivers the jack to start the game. The winner of the previous end delivers the jack to start the next end. Once in play, the jack may be knocked by a bowl to a new position.
Note: The jack can now be turned over to the opposing team.

Lane: All games are played within Lanes that are at least 14 ft wide. The lanes for a given game or tournament are designated with markers on the edges of the green. This way, multiple games can be played simultaneously on one green. Bowls that come to rest out of their lanes, are Dead Bowls and are removed from the end.
Lead: The person who starts off the play. Also places the Mat and rolls the Jack if their team "has the mat".
Mat: The actual mat that is placed by the team losing the last end, to start the next end. This is also known as having the Mat. The team with the mat always rolls the Jack. Newer rules allow the winning team to give away the mat, thereby losing control of the Jack, but ensuring they have the final bowl of the end (the Hammer). The mat is placed on the center line of the rink by the lead bowler of each end. One foot of the bowler must be on the mat when delivering the bowl or jack. A second mat is used at the other end of the rink for the return end.
Measure: When bowls are too close to visually decide which one is closer, it is known as a measure. Players carry special lawn bowls tape measures to do this. The distance is irrelevant so the tapes are only used to see who is closest.
Narrow: Bowler didn't start out far enough from centerline to the Jack.
Pairs: Bowls games in which each team has a pair of players ( a Skip and a Lead)
Points: Whoever gets their bowl(s) closest to Jack at conclusion of an End.
Potato Bowl: A badly thrown (or released) bowl that hops, skips and jumps.
Promoting a Bowl: Pushing up one of your team's bowls to a better position.
Rink: A rink is comprised of several features, namely Ditches, Bank & Side Lines. It is the
lane on the grass court playing surface. Often 15 feet wide from one end to the opposite end. Each Rink is defined by markers on the edge to clearly define the lane.

Rinks bowls: A bowling game in which there are 4 players per team a Skip, a Vice, 2nd Lead and a Lead.. Typically then players only use 2 bowls each.
Side Lines: Side lines are not marked on the rink, but are indicated by markers on the face of the bank. Bowls that travel beyond the sideline but curve back in are still in play.
Skipper: Team captain or Skip who always plays last. This person is usually the most experienced player, who also guides the strategy.

Shot Bowl: The bowl closest to the Jack.
Tie: When the two closest bowls are both exactly the same distance from the jack and belong to opposing teams, even after measurement, the end is declared a tie. (Note: Unlike old conservative English clubs, the men never ever wear ties at our club - not even for Xmas dinner!)
Touchers: Bowls that hit the Jack. These bowls are marked with chalk and remain "alive" even if they are in the ditch.
Trial Ends: Formal practice ends, usually only allowed at the start of a tournament, in which each team rolls 2 bowls down and back to get a feel of the green. Such ends do not count in the scoring.
Triples: A game in which each team has 3 players on their team - a Skip, a Vice and a Lead. Typically each player then only uses 3 bowls each.
Up: When your team does have the Shot Bowl, you are considered to be Up. You may be Up by one or more points.
Vice: The person who plays after the Lead and is responsible for deciding the winner of a head, and recording the results.
Weight: The amount of speed applied in delivering the bowl from the mat to the Jack. "Heavy" weight means that the bowl stops beyond the Jack, while "Light" means that it stops short of the spot desired.
Wide: The bowl is started too far out of the centerline to the Jack (also called taking too much "Grass").
Wick: When a bowl bounces off another bowl. (This term is derived from curling).
Woods: An old term for bowls.
Yard On: A shot delivered with an extra degree of speed to displace or disturb other bowls in the Head with intent of killing the End.
