Build a command
A pawn moving onto a friendly knight forms a captain. Captures by the captain and its commanded pawns grow its allowance.

Can you find the sequence that changes the battle?
Fuse a pawn with a knight, command a growing team, raise vulnerable offspring and prepare new territory. Choose camp preparations and carry two surviving captains or royal heirs into the next match. Their names, families and deeds follow the campaign.
User value
Find a sequence worth remembering.
Chess becomes a story of command, family and territory. Take your time, try an optional tactical exercise, or watch a recorded campaign unfold.
Raise the next generation
Compatible parents swap places and create one or two children on free back-row squares. Newborns need two of their own turns to grow.
Carry a small legacy
Five victories complete a run. Your land grows after each win, while two shared places carry surviving captains, princes or princesses forward.
Features
Eight armies, one set of rules.
Romans, Greeks, Aztecs/Mexica, Mongols, Japanese, Norse, Egyptians and Persians share readable chess silhouettes and an antique-map world.
- 01
Command on the board
Select a piece to see its moves, captain formation and mating options. Actions happen immediately; a highlighted End turn button lets you skip remaining pawn commands.
- 02
Follow your units
Read names, family links, achievements and memorials. Battle reviews explain real captures and command growth, with before-and-after replay positions.
- 03
Learn or watch
Eight optional lessons teach actions, threats, protection and newborn timing. A smaller first battle provides room to experiment. Live Watch Mode and recorded replays let you observe without playing.

Product concept
Each victory changes the next board.
The nearest two rows belong to each army. The middle four are a shared battlefield.
Earn the frontier
Victories unlock two more columns for the next match, up to sixteen. Pieces must prepare new home squares before children can use them.
Protect the captain
When a captain is captured, its pawns survive and become free. A team pawn can still promote normally at the opposite end.
Prepare your next battle
Keep formation, advance a commander, or send a rook to prepare nursery space. Inspect the exact position before choosing the encounter. Territory lasts for this run.
