Imagine you're just chilling, sipping your favorite cavern coffee, when a spy rushes in with terrible news: a hero is on the loose and wants to invade your lair! In Oh My Lair!, you step into the shoes of this dungeon lord who must prepare for the onslaught. The goal is straightforward but tricky: you must stop this hero from reaching your sanctum. To do this, you'll command your minions to conquer territories and gather the vital resources needed to summon powerful creatures to act as your defenders.

The gameplay is fast-paced and structured into four key phases. First is the upkeep phase, where your minions return to your side. Next is the order phase, where you decide whether your minions will expand your domain by conquering new regions or focus on collecting resources from the areas you already control. Once you've gathered your loot, it's time for the buy phase, where you spend resources to summon monsters and strategically place them along the hero's path. Finally, the hero takes their turn: they move one step closer to your lair, battling any monsters you've placed in their way. If you can defeat the hero before they reach your cave, you win! It's a game of resource management and strategic positioning, all with the ultimate convenience of a Print & Play that only requires a single sheet of paper and a few standard dice.
