Thinking in Two Hands

The heart of Siamese is that your two hands are not fixed at the deal. You may move concealed tiles freely between your own two racks at legal moments. A tile you drew hoping to help your first hand can just as easily slide over to complete a group in your second.

What can move, and what cannot

• Concealed tiles can move between your two racks as often as you like.
• Exposed tiles cannot. Once a group is face-up on a rack, it is pinned to that hand for good.
• Tiles never cross to your opponent. Moving tiles is strictly within your own two racks.

Balancing the two hands

Good Siamese players think of their tiles as one shared pool feeding two goals. Early on, keep both hands flexible and let the tiles tell you which pattern each rack wants to become. If one hand is racing ahead, you can steer helpful concealed tiles toward the one that is lagging so they finish closer together. Because you need both, a single strong hand next to a hopeless one wins you nothing — the trick is keeping both alive.

This is also where the mental effort lives. You are tracking twice as many groups, twice as many "tiles I still need," and constantly asking: does this tile serve hand one, hand two, or neither?
