I am always looking  for a new tower defense game. I’m almost always playing one and there are only so many times that I can play another tower defence game that looks and acts very much like the last tower defense game I have played. Spira Defence is something different, but at the same time it retains the essence of what makes tower defence games fun and challenging.

It is a single screen game with five open slots for upgradeable towers in the middle. Enemies enter on the edges and find their way to the centre, sometimes in a spiral, sometimes not.

The free version has 72 levels, whilst the premium version has unlimited levels as well as being ad free.

I picked up Spira Defence a few times before it sunk its claws in. It’s not a visually appealing title, by now I really should know that some of the best games aren’t and strategizing with coloured dots, squares and circles did not create an instant appeal the first time I played a level.

It stuck with me though and after picking it up four or five times, things suddenly clicked in and I played for a marathon session trying to beat my previous progress. As it is essentially one very long (or infinite) level, some of the replay value is lost by having limited content that does get boring after a while. It has quite a bit of mileage for a free to play Android game.

Spira Defence is a charming little tower defense game with a twist that makes it challenging and fresh without compromising the ground rules of the genre. Its user interface is not very user friendly, but looking past that its simplistic visuals and controls make it very accessible. I thoroughly enjoyed playing it and I think fellow tower defense enthusiasts probably would as well.

The game review is based on the Android (exclusive) version of the game. This article was first published on 22 August 2013 and is no longer being updated. Information may be out of date or otherwise inaccurate due to the passage of time.
