Lawn Bowls Trial Ends: How to Read the Rink Before Play

Trial ends are more than a warm-up. They are your first chance to learn the rink, compare both hands and agree how your team will begin the match.

Under the World Bowls Laws of the Sport, one trial end is normally played in each direction before a new game. Domestic conditions of play may reduce that, so check the event rules before assuming you have two.

Start by testing both hands

Use the opening bowls to see how much grass each hand needs. Watch where the bowl begins to turn, whether one side holds its line longer and whether the finish is consistent. A hand that looks wider is not automatically worse; the best hand is the one your team can repeat with confidence.

Judge pace, not just position

Notice how much delivery weight reaches a short, medium and full-length jack. The result of one bowl can mislead, so compare several deliveries and watch the opponent's bowls as well. Look for shade, moisture, worn lines and ends that play differently in opposite directions.

Read the wind early

A crosswind can alter both the arc and the finishing speed. A headwind may demand more weight, while a tailwind can make a familiar delivery run. Treat the first trial end as a forecast, then use the return end to see whether the effect changes in the opposite direction.

Know what trial ends do not decide

Trial ends do not score. Bowls can be removed after they come to rest, and a jack moved by a bowl is returned to its former position. The side starting the first trial end places the mat and jack; the opponents start the second. Once the first bowl of a trial end has been delivered, its mat-to-jack distance cannot be changed.

Leave with a simple opening plan

Before scoring play begins, agree on three things: the preferred hand, a comfortable opening length and the safest place for the first two bowls. Keep the plan short enough to remember, and change it only when the evidence on the rink says you should.

Record what the rink taught you

A digital scorecard can preserve more than the total. Note the preferred hand, jack length and any pace change so the lesson survives beyond the first end. WGTS combines scorekeeping with camera-assisted measurement on compatible devices. Try WGTS for iPhone or WGTS for Android.

Rules note: domestic regulations and competition conditions can modify trial-end arrangements. Check the documents for your event.
