Karakuri Ninja Run

Floors give way. Walls spin. Ceilings come crashing down. Race through trick-filled ninja houses in this pixel-art ninja action game.

Read the traps and run for the deepest room.

■ 400 houses across 50 regions From teahouse streets to snowbound post towns and a clock tower, every region has its own scenery. In the last house, an oni lies in wait.

■ 24 jutsu Burn traps away with fire, strike oni down with lightning, summon a giant toad. Carry up to four jutsu. The set you choose changes how you run.

■ 20 oni A monk who hurls anchors, a great ape throwing things from the hot-spring steam, a great tengu who has learned every oni's moves. Spot their habits and strike when they slip.

■ Pick a boon in every room Clear a room, then take one of three: a log that takes a fall for you, Double Koban, an Odd or Even dice bet. Your boons stack until you leave the house.

■ Secret rooms and sealed windows Behind suspicious walls sit hidden rooms full of scrolls and koban. Pry open a sealed window and you have found a shortcut.

■ Run as the oni you defeated Spend the koban you bring home in the Shop on upgrades, jutsu, and outfits, including some that let you take the shape of an oni you beat.

■ Endless House The house never ends. How far can you run?
