One fortress against the horde

An Eastern fortress stands alone on the steppe, and the Mongol horde is riding in. Its archers shoot on their own: your job is the build. Between the waves, spend your gold on random cards and turn one fortress into a wall of fire, stone, steel, water and wood.

Towers that fight on their own

• 95 towers in four tiers, from Common to Legendary. Each one stands on the fortress and shoots by itself, in its own element, at its own rate.
• Ballistas and crossbows, slings and twin bows, catapults and lightning rods, shrines that call up a phoenix or a golem, harpoons that strip the riders' armor.
• No limit on how many the fortress holds: when the walls are full, towers ring round it.

A shop of random cards

• Towers on the left, upgrades on the right. Reroll what you don't want, lock what you're saving for.
• An upgrade raises an ability on every tower that has it: one burn card makes every burn hotter.
• Everything stacks. Build into an element's focus, then its ultimate, one a run: Armageddon, Petrify, Blade Storm, Tsunami or Wrath of the Forest.

Elements against armor

• Every element beats one armor and is weak against another, and the chart beside the board shows which: Fire melts Metal, Water puts out Fire, Wood breaks Earth.
• Each wave rides in its own armor, and later waves mix them. Mix your towers to answer the horde.

Two ways to play

• Circle: the horde rides laps round the fortress. Let more than 100 stay alive and you're overrun.
• Tower Attack: the horde charges from every side. Keep the fortress standing.

The Great Khan

After 30 waves the Great Khan comes himself. In the Circle he can't die: deal him all you can in a minute. In Tower Attack, bring him down before he brings down the walls. Beat him and the run is won. It's meant to be hard.

Made for phones

• Landscape, made for your thumbs: tap a card to buy it, hold it to read it whole.
• A run you leave part-way is kept: pick it up where you stopped.
• Music from period instruments: zither, harp, fiddle, bamboo flute, war drums, gongs and throat singing.
• Settings for text size, high contrast, reduced flashing, screen shake and more.
• No ads, no purchases, no account, and no internet needed.

Meet the horde

The riders in the order they show up. Each wave rides in one armor, and the riders wear its colour; later waves ride in with traits: armored, blessed, evasive, immortal, splitting in two.

The fortress grows

It grows with its towers.

The elements

Each of the five beats one armor (×1.5) and is weak against another (×0.5), as the chart beside the board shows. Normal is the archers the fortress starts with; Divine is the Divine Bow, a Legendary tower.
