One more scroll—or one more flip? Adversary is a quick memory-matching game with a Danger card that you don't want to find. Flip cards, remember what you've seen, and match the pairs. The rules feel familiar, but every flip carries more tension because Danger is hiding somewhere on the board. PLAY YOUR WAY Two game modes, each with five difficulty levels Bigger boards and more challenging layouts Different Danger setups across difficulties Try Extreme mode with instant Game Over when Danger is revealed TWO GAME MODES: Classic: The original Adversary experience. Flip cards, remember their positions, find every pair, and try not to reveal Danger. Shuffle: First, memorize the board. Then watch the cards shuffle before the game begins. Find the pairs from their new positions — and if you reveal Danger, the remaining hidden cards may shuffle again. CHASE YOUR BEST Track your best score for each difficulty Can you beat your best? MADE FOR QUICK ROUNDS Adversary is easy to pick up when you have a few spare minutes—waiting for a bus, standing in a queue, or reaching for your phone out of habit. Instead of opening another feed, play a focused round and see how far you can push your score. START FREE Classic starter is free to play. Unlock all game modes and levels with one lifetime in-app purchase. No subscriptions. Just matching pairs, hidden Danger, and the question behind every flip: Is this the one?

It starts with a grid. Then you build a kingdom. Keepsweeper mixes Minesweeper-style deduction with a living, real-time fantasy kingdom. Read the number clues. Send workers to uncover tiles. Turn a small clearing into farms, homes and defenses. Then decide whether you're ready to wake the dragon. A LITTLE KINGDOM. BIG POSSIBILITIES. Build an economy that works together. Windmills support farms. Blacksmiths equip your soldiers. Chapels keep the army fighting. Discover combinations that turn a modest settlement into something wonderfully overpowered. EVERY SQUARE HAS A STORY Hidden gold, treasure chests, goblin lairs, crypts and sleeping dragons wait beneath the grid. Explore forests, cross lakes and settle mountain country. Dig carefully. The numbers are trying to tell you something. CHOOSE YOUR ADVENTURE Follow four quest paths: Dragon Hunt, Royal Treasury, Reclaim the Realm and Rival Kingdoms. The full game adds two twenty-level campaigns: Into the Badlands, with ruined roads, buried archives and Ancient Gates, and Beyond the Pines, where outlaw strongholds and dragon-summoning wizards hide in the northern forests. Head into the Wilds for a larger expedition, or see how long you can survive endless Siege. A NEW REALM EVERY DAY Explore a shared Daily Realm with special objectives. Record your victories in the Realm Journal and earn Royal Seals for first completions. MAKE THE NEXT RUN YOURS Earn Royal Seals and spend them in Research. Unlock new buildings, upgrades and permanent Passives for future runs.
