Y Siambr

Boom Cymru for S4C, 7 March to 11 April 2019 (6 episodes in 1 series)


A pair of teams compete to solve puzzles and problems in a deep cave. Only the better team can win...

A disused slate mine has now been converted to house adrenalin pursuits kind of place: there are chances to abseil, walk along tight ropes and rock faces, and trampolines. These existing facilities are used for the challenges in Y Siambr.

Challenges on the show include one where contestants find pieces of a jigsaw, then pass them to their team-mate who assembles the picture high up.

Y Siambr The bouncy jigsaw game in progress.

There's a perilous walk along a rock-face, and so many zip lines that The Krypton Factor is envious.

The winning team tries to escape from The Chamber, a series of skill, mental, and physical challenges against a tight time limit.

Y Siambr The signature game: push all buttons at once.

Aeron Pughe hosts the show with a dry wit, he "encourages" the teams and raises an eyebrow with us viewers. The enclosed space lends itself to some high-quality camera work, and every game is told clearly and precisely. It's made with great care, and fun to watch.
