Orcs attack

So Orcs Attack is this tower defense game that mixes in some card collection stuff, and honestly it's pretty straightforward once you get the hang of it. You start each battle with a castle at one end of a winding path, and waves of enemies come from the other side. Your main job is to place towers along that path to stop them before they reach your castle. The basic loop is: you get a hand of cards--these are your towers, spells, and hero units--and you drag them onto the battlefield. Each card costs elixir, which refills over time, so you're constantly deciding what to place and when. Early levels like "Greenfield Plains" just throw bandits and basic orcs at you, so you can get away with arrow towers and a few fire traps. But around world two, things get nasty. You start seeing shielded orcs that need magic damage, and fast wolf riders that slip through if your towers aren't positioned right. The difficulty ramps up by introducing new enemy types that counter whatever strategy you were relying on. For example, those shielded guys make physical towers useless, so you need to swap in arcane towers or use a hero like Elara the Mage to debuff them. Later on, there are flying harpies that ignore ground towers entirely--you need specific anti-air units like the ballista tower or a ranger hero. The satisfying moments come when you pull off a perfect chain of upgrades mid-wave. Like, you save up enough elixir to level up your main cannon tower just as a boss wave hits, and that upgrade lets your towers target two enemies at once, clearing the screen. Bosses themselves are a highlight--each world has a named one, like "Grom the Siegebreaker" who has a giant club that smashes your towers if you don't focus fire him. You have to micro your heroes to retreat and re-engage, which feels active, not just passive placement. The card upgrade system is where a lot of your brainpower goes outside battles. You earn chests from winning--bronze, silver, gold--and they drop duplicate cards for your towers and heroes. Combining duplicates levels up that card, increasing its damage or health. There's also a passive skill tree for your kingdom that unlocks things like extra starting elixir or faster hero respawns. The store refreshes daily with specific cards you might need, but you can also watch ads for a free chest every few hours, which is a nice little boost. What keeps me coming back is how each battle feels different based on the random card draw and the enemy composition. You might get a perfect hand for a rush strategy one round, then struggle with a defensive spread the next. The game doesn't telegraph what's coming--you have to adapt on the fly. And the city expansion part is pretty hands-off; you just spend resources to build new structures that give passive buffs, like a blacksmith that increases tower attack speed. It's not deep, but it's another thing to chip away at. The real meat is in the tactical choices during those three-minute waves, where a single misplaced tower can lose you the match. There's no final victory screen that wraps everything up--you just keep climbing worlds, each with a new theme and tougher enemies, and the loop stays solid.
