Spy Slots?

[LabMonkey]

So how do you get more slots to build spies exactly? I'm going for a science victory and France is pissing me off sabotaging my stuff every few turns and I need some more counterspies. I've already built one spy it just says I have 1/1 spies so what opens up more slots? Thanks.

Just build more spies in your city production queue.

It's not that simple. You unlock more with more techs from the tech tree. You may not know this but if you open up the tech tree make sure to hover your mouse over each tech bar. For some of them there is additional info for what else unlocks besides what's shown by the icons.

I think they had planned to have spy icons on the bars but maybe they didn't get around to it in time.

ok, so it's kind of like unlocking the free envoys with civics. I played for a bit longer and unlocked another slot but still didn't know how I did it. Thanks
