do contestants not in the final keep the money they built up

No, only the one in the final round gets either the £10k or the money they have accumulated.

...... in addition to shoota's post, the final contestant could end up with nothing, if they take the trade-off and don't get the "star token" to drop.

But they do keep the mystery prize that they won.

Yep, you're right with that one gollob :)
