The Firm (iOS, 69p, Sunnyside Games) is a stockbroking take on a Tetris-lite “twitch” title – putting lightning reflexes front and centre, while taking an obvious – if unusual in gaming – swipe at the machinations of capital and trading. The game presents a freshly qualified stockbroker arriving at a sky-high office, pot plant in hand, to start a career as a big-money banker. From there an endless stream of stock prices flash up on a ticker – the task is to sort them into buy and don’t-buy piles. Green stocks going up and red stocks going down are to be bought, green going down and red going up are don’t-buys. Simple to be sure – but mighty tough once it gets moving, even with the various power-ups available. Game over is marked by your avatar flinging himself through the window to the concrete below. The next run-through begins with the smashed window still visible in the background… Give it a few tries and you’ll know the feeling.
