Since I know some people are curious about how this exactly works.
Eurogamer said:Each attempt at a game round (think, a go at a Bejeweled level) costs you one heart, whether you win or lose. Pokémon Shuffle starts you off with five hearts.
Every 30 minutes you accrue one extra heart, up to a total of five. If your total is ever above five - for instance, if you have chosen to buy more using gems (obtainable with real-world money) - then the auto-accrue system prevents you from earning more.
Jewels, which are the things you'll actually pay for with real-world money, can be exchanged for extra in-game hearts and coins, the latter of which is Pokémon Shuffle's other currency. Jewels can be bought in various sized lumps, ranging from 89p for one up to £42.99 for 75.
One jewel is worth five hearts or 3000 coins, enough for a moderately powerful item. The more jewels you buy and spend, the better the conversion rate.
Coins can otherwise be slowly accrued by beating matches (100 per match) or in larger amounts from bosses.
Jewels are also - rarely - found in the game itself. We were awarded one for completing Shuffle's first main area, for example.
Eurogamer said:Rounds must be completed within a certain number of moves, although if you are struggling you can buy more moves or other help items with in-game coins.
The fewer moves you use the more likely it is you will catch the wild Pokémon at the end, or you can choose to buy stronger Pokéballs to raise the likelihood of capture.
Eurogamer said:Run out of moves altogether and the battle comes crashing to a halt. But there is a way out: you can spend a jewel to buy five more hearts and continue the battle where you left off, or lose your progress altogether.

I ran out of hearts after around 45 minutes on my first play session - but much of this was me just running through the game's tutorial, which includes dollops of free time and moves to keep you playing. Subsequent play sessions will last a lot less time.
