33. Clash Royale
Supercell’s follow-up to Clash Of Clans ingeniously makes the complex feel so simple even a toddler could grasp it: card collecting, tower defense and real-time strategy all rolled into one intuitive, easily navigable, deeply strategic package. Here your decisions matter as much as they do in, say, Hearthstone, but its speed and accessibility cunningly convince even fresh-faced players that they’re instant experts. The final minute of every Elixir-focused battle is genuinely exhilarating as you sling every last card at an opponent in the hope of taking down its King Tower, while outside of matches the unlocking of prize chests every four hours keeps you checking back in.
