A few weeks ago I introduced a jenga/fate mechanic to our game and it has been quite fun. The table goes silent when ever anyone pulls on the blocks of fate.
I think of the jenga tower as portions of fate the pcs can pull at to their advantage. Also any BBEG with fate points can use the the tower. Toppling the tower has dire consequences, and once you have committed to it you cannot stop. Some of the towers benefits duplicate those of fate points. If you choose to use the tower and fail, you cannot then use a fate point. You can however combine the benefits of multiple pulls
The options are as follows
Price | Benefit
1/per | +5% on a skill roll for each block pulled
2/per | +1dmg on a single attack, must be made before attack roll
1/per | +1 pen on a single attack, must be made before attack roll
3 | Reroll the skill test, can only be used once per test
10 | Counts as the effect of burning a fate point, you are still alive
Also to prevent people from simply stopping when the tower gets to perilous i have a end of game chart. Should the tower topple at the end it is a less sever consequence. Ie last game it was +100xp if the made it, -100xp if the failed…. they failed!
One player is selected as the roller
1-10.) All is well, The Emperor smiles upon your group, high fives all around. refresh all spent fate points
