         "intermedium": "Intermedium (aka, Stepping Stones) is a 1974 game designed by Matt Crispis. This is a stack sowing game, where players try to surround the opposing home-base. Stacks only move diagonally, and each army starts in a different diagonal color, so they can never cross over (like two bishops at different square colors). Pieces are captured by enclosure, surrounding all orthogonal adjacencies of an opponent stack.\n\nSome words from the author: \"[Intermedium] is simple to learn, but may lead to complicated situations that require deep analysis and forward thinking. Single pieces do no move, but they are useful a stepping stones for your captures. And they may become alive by putting another piece over them. Before you master the game, avoid early attacks against the City that  may prove costly. Build up your strength gradually and evenly by dominating, if possible, the center. You should also avoid building 'formidable' stacks of six or more pieces - if taken you may lose the game at one stroke. Leave some forces behind to defend your City in case of emergency.\"",

Invector simply combines two basic, off-the-shelf ingredients: orthogonal, adjacent capturing moves, and orthogonal, adjacent moves closer to center.",

+        "killallgo": "The Attacker, whose stones are already on the board when normal play begins, wins by preventing the Defender from ever making a living string. The Defender wins by making one string that cannot be captured. There is no scoring.\n\nStones are placed and captured as in Go with Tromp-Taylor clearing: after a placement, opponent strings without liberties are removed, then your own string if it has none, so multi-stone suicide is legal. Positional superko applies: no placement may recreate any earlier position of the board. Either player may pass; if both pass in a row, the Attacker wins.\n\nThe Defender wins as soon as one of their strings is unconditionally alive: pass-alive by Benson's algorithm, meaning the Attacker could never capture it even with unlimited consecutive moves. That is the only way to win as the Defender. A string that is merely alive in seki or in ko does not count, so the Defender must keep playing and turn it into a string that cannot be captured at all.\n\nThe Attacker wins as soon as that has become impossible. Stones of the Attacker that are unconditionally alive can never be removed, and no point next to one of them can ever lie in an eye of a living Defender string. When no area left over by those stones holds two points that are neither next to each other nor next to those stones, there is no room anywhere for the two eyes a living string needs, and the game ends. The check does not recognise every lost position; when it does not trigger, play simply continues.\n\nOpenings: with Pieboxing, the players take turns placing Attacker stones until one of them takes the Attacker side; the other player then moves first as the Defender. The handicap opening works the same way, except that Player 1 (the stronger player, so seat the handicap giver first when creating the challenge) first sets the number of handicap stones and Player 2 starts placing; if Player 2 takes the Attacker side, they place that many extra stones at once. The classic opening uses the traditional 17-stone position on the 19x19 board, with the Defender (Player 1) to move. In the simple pie, Player 1 places any number of Attacker stones and Player 2 chooses a side. In the generalized Hoctaph's pie, Player 1 chooses two batch sizes (each at least 1, together at most the number of points minus 2, neither more than twice the other), Player 2 decides who places the first batch, the other player then chooses a side, and the Attacker places the second batch. In every opening the Defender makes the first normal move.",

When done, click on an empty cell or use the Complete Move button.\n\nThe coordinate system is adapted from the coder's coordinate system for Hive, a game on an unbounded (but still reasonably sized) hex board.  The y axis is labeled with Cartesian coordinates (positive and negative integers).  The x axis is labeled with letters in alphabetical order, with the origin at (m, 0).  If motion on the x-axis exceeds the confines of the alphabet in either direction, the letters are prefixed with another letter (z is followed by aa, ab, ac, etc., and a is preceded by zz, zy, zx, etc.).  The game is not expected to reach a width that requires more double coordinates, but for the record, az is followed by ba, za is preceded by yz, and so forth.  The board cannot reach a size that would result in ambiguity.",
