4. Marvel Puzzle Quest
One for the mobile crowd and a puzzler dossed out in enough Marvel duds to keep the smiles coming, as the House of M's take on the beloved Puzzle Quest formula fits like a glove, giving you access to a tile-based puzzler whereby you'll do battle by lining up various gems to dole out the damage. Of course being a mobile title it's positively littered with micro-transactions that relate to two specific in-game currencies you'll amass over time in varying amounts, but again there's a significant chunk available for free, and as you're forever picking from a random selector of possible unlocks, you could end up with the premium fighters over time anyway. All that said, the reason this is included is down to the gameplay, and when you've got your specialist team of three interchangeable heroes trading blows as their own symbols line up on the tile-set (also choosing who gives and takes damage) it's a brilliant system that really should've made the leap to consoles.
