We do like a good word game, and Capitals is a very good word game. There are echoes here of Letterpress (mentioned elsewhere in this feature), in the sense that Capitals combines Risk-style land-grabbing with the need to create words from a jumble of letters. However, while Letterpress for the most part benefits players able to fashion lengthy words, Capitals is more about where the letters you choose to use are located.
The game plays out on a hexagonal grid, either with two players using the same device or battling it out online thanks to a Game Center match-up. All letters on the board can be used to create a word, but only those attached to your territory flip to your colour on submitting a move. The important thing is to keep your capital surrounded by territory rather than letters. If you don't and your rival's move includes letters adjacent to your capital, it's captured. They then get a free turn, and since the objective of the game is total and utter annihilation, that extra move is often enough to gift victory.
For no money at all, Capitals is one of the best games around for word-game nuts, although we'll admit to being a smidgeon miffed about the ad model; in miserly fashion, it only gives up a solitary game for every advert watched. Still, since a game can often play out as a days-long tug o' war, the ads are hardly a huge drain on your time for what you get in return.
3. Threes! Free
Every platform needs its perfect puzzle game, and on release Threes! made its claim to be the iPhone's. As with all brilliant examples of the genre, Threes! has at its heart simple mechanics, which in this case involve merging cards within a tiny four-by-four board. But it's the details that propel Threes! beyond the competition.
The idea is to match numbers. Slide a blue '1' into a red '2' and they combine to become a single '3' card. Two 3s make a 6. Two 6s make a 12. And so on. The snag is that every move you make slides every non-blocked tile on the board as well. If you're fortunate or have planned ahead, this can result in several merges in one move; if not, you end up with a mess to clear up. And since after every turn a new card enters the board in a random spot on the edge you swiped from, planning is key.
It takes a few games for Threes! to properly click, but once it does, it never lets go. You'll be dying to see new cards (each is infused with a unique personality), and will soon spot how reaching higher-numbered cards boosts your score substantially. The free-to-play aspect is also generous: watch a video ad and you get three more games in the bank, which can be built up into a substantial reserve.
