Tension on a Timer: How Progress Clocks Keep Your Game Exciting

Word up my homes.

Today we’re going to talk about “Progress Clocks”. I think these were first introduced by John Harper with Blades in the Dark. They weren’t the first solution to the particular problems they address, but I do think that they’re perhaps the most elegant.

You’ll understand in a bit.

Why Use a Progress Clock?

You’ve all felt that, right? That anticlimactic feeling that comes from presenting your players this mountain to climb, only for them to simply roll Athletics and pass. “Well done, you’re at the top, well that was dull”. Extreme example I know, but I’m trying to illustrate a point here :)

Experienced GMs might have other techniques for circumventing this problem, but Progress Clocks are for turning a single mechanical success or failure event into something that matches its theme. They’re for showing players exactly what the stakes are, and for managing their expectations regarding how they’re currently performing.

They prevent a couple of failed rolls from completely derailing the players’ current plan.

How does a Progress Clock work?

You draw a circle, and you divide it into a number of pizza slices. 3-6 slices is common, but you can go higher or lower to taste.

You then label that circle with the event that WILL happen once the clock is filled in, and you put it out in front of the players so that they understand what’s at stake.

Then as relevant in game activity take place, you colour in those pizza slices, representing the final event drawing closer. Depending on the sheer influence of the activity that has happened, you may wish to fill in more than one slice. You should also be open to the idea of filling in the entire clock in one go if the situation justifies it - You might have thought that something is quite big and complex and worthy of 8 slices, but your players might come up with something that deals with it in one swoop. You’ll know when it happens, don’t impede this.

I should note, it’s not just in game activity that might fill a clock, it might literally represent the passage of time itself.

When do you use a Progress Clock?

You know when you’re running a game and the players want to do something, you might call for a check, and if they succeed, happy days? Well, Progress Clocks are for when the action is too big or significant that it’s success or failure should fall down to a single mechanical event like a dice roll.

Likewise, imagine your players trying to break someone out of jail and there’s this really cool stealth session. Unfortunately they just failed a stealth roll and tripped over in front of a guard, so now the guards are alerted to their presence, and unless you the entire place to come down upon them over a simple misstep, you’ve got to tie yourself in narrative knots trying to justify why the first guard hasn’t just raised the alarm.

Or imagine if your players are trying to accomplish something before this other thing that they cannot affect happens. You might have two clocks here, one for the players progress and one for the other event.

What are the Types of Progress Clock?

Ticking Bomb

The Ticking Bomb Progress Clock represents how long until something terrible happens. In that time, they need to find a way to circumvent the problem or to prepare for it. This is the classic heist Progress Clock, representing how many mess ups PCs can make before the guards are alerted - in the meantime the PCs want to be in and out.

Competing

Competing Progress Clocks are used to show the progress of two separate events that do not influence each other. For example, the PCs might be trying to evacuate the village in the valley before the Dam breaks. The PCs might advance their clock by sounding the alarms, and guiding people across the bridge, and the Dam’s clock might advance as you roll a check to see if the crack in the damn wall is growing.

Tug of War

Possibly the most complicated to explain, there are two possible event outcomes, and you don’t start these clocks empty. Tug of War Progress Clocks represent two outcomes that DO influence each other. So if the PCs were running away from a monster, as the PCs succeeded in their checks they might fill the clock, and as they fail, then the clock empties. The outcomes in this case would be either a successful escape, or the Monster catching up to them.

Conclusion

Nice, hopefully that makes sense to you. If you could use more information, checkout Sly Flourish’s video for extra guidance, or reach out to me on Bluesky.

By the way, I’m currently making a one shot adventure for GOZR called The Rusted Colossus, about a giant old mech that’s been uncovered in the desert. I’m planning on referencing this post, so that if people need pointers on Progress Clocks, they’ve got them. If you’ve come from there - this is time travel. Hello future people! I hope my adventure came out well :)
