Two roped beasts, one field of stones — never let the rope snap
Gorilla UA
A broad stretch of water, a scatter of flat stones, and two pack beasts tied together by a single rope. Thranvokis Bound is a puzzle of shared footing: neither beast crosses alone, and neither may be left behind.
You move them by tapping. Tap the stone a beast is standing on and it bounds forward to its next stone. Where the stones fork, tap a stone just ahead of a beast instead, and it takes that line rather than the other. That is the whole of the control scheme — the difficulty lives entirely in the order you choose.
The rope is what you are really playing against. Send the leader on too many times in a row and the slack runs out, the line pulls taut, and the crossing fails. So you alternate: a leap from the one in front, then a leap from the one behind, reading the stones ahead to see which beast can afford to go next. When the slack grows dangerously short, look for a wide stone with room for both animals, rest them there together, and win back the length you spent.

The field itself is not kind. Some slate is sinking stone and will not hold weight. Some perches take a single beast and no more, which means stepping onto one commits you to bringing the other round another way. And some inviting branches simply end, leaving a beast stranded at the water's edge with nowhere to bound but back. Learning to recognise a dead end before you have spent your slack reaching it is most of the skill.
There are twelve crossings. The early ones teach the rhythm of alternating leaps on a forgiving line of stones; the later ones ask you to plan several bounds ahead, to decide which of two forks to commit the leader to, and to spot the one wide stone that makes the far bank reachable at all. Most crossings have a single clean solution and several tempting routes that look right until the rope tightens.

It is a quiet, deliberate sort of puzzle. You can study a field for as long as you like before the first tap, and there is nothing to rush you once you begin — only two tired animals, a rope between them, and the stones you chose for them in whatever order seemed best.
