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. Discover treasures that change the rules: sunbeam-firing towers, floating settlements, unlikely allies and creatures you probably shouldn't have disturbed. FRIENDS, RIVALS AND YOUR OWN WORLDS Play online with two to four players. Fight for the last Keep standing, form teams, face AI kingdoms together or hold the line in Co-op Siege. Share an invitation link and friends join your game for free. Build and play your own scenarios in the Map Editor. OLD-SCHOOL WINDOWS. LIVING PIXELS. A familiar beveled interface opens onto busy little worlds. Workers harvest. Soldiers march. Dragons breathe fire. An adaptive fantasy soundtrack follows the action. Pause solo play whenever you need a moment to think. TRY IT. KEEP IT. Play the first two levels of Dragon Hunt, Royal Treasury, Reclaim the Realm and Rival Kingdoms for free, with unlimited randomized replays. Try one Daily Realm for free, with unlimited retries of that selected realm. One optional purchase unlocks the full game, including the remaining quest levels, Into the Badlands, Beyond the Pines, Daily Realm, Wilds, Siege, hosting multiplayer games and Map Editor. Solo quests, Wilds, Siege and local custom maps can be played offline. Daily calendar updates, optional reminders, online multiplayer, community maps, purchases and restoring purchases need an internet connection. Progress is saved on your device.
