The Game, BBC Two, 9pm

John le Carré should probably sue the BBC over this stylish spy drama, so brazenly have they appropriated his world of tradecraft and dead letter drops. No matter: Sarah Dollard's 1970s-set series is great fun. Every time Paul Ritter's Bobby Waterhouse refers to spy boss Brian Cox as "Daddy" you want to snigger, but there's a great counterpoint in Tom Hughes's performance as the darkly troubled Joe Lambe. In tonight's third episode, the team continue to investigate Operation Glass and Arkady (Marcel Iures) reveals the name of the latest KGB sleeper agent - Russian speaker Kate Wilkinson, played with gusto by Rachel Stirling.

The Secret World Of Tinder, Channel 4, 10pm

If you're still using a dial-up internet connection and a mobile that only makes phone calls, you probably won't have heard of Tinder. If so, here's the gen: it's a location-based app which allows people to find other social media users with similar interests and, er, proclivities and who, importantly, are nearby. Mostly it's used either for dating or for what used to be called casual sex but is now known as "a hook-up". Got that? Excellent. Against this slightly salacious backdrop, Channel 4 gives Tinder and its users - or "Tinderellas" if you prefer - the documentary treatment in a programme which looks at both the benign and the potentially dangerous side of dating 21st century style.
