<ルービックケージ ルール説明> 2人のプレイヤーは3色のキューブを各4個ずつ計12個持ってゲームが始まる。 プレイヤーが交互に3×3×3のケージに手持ちのキューブを交互に上から入れていく。中央マスにはキューブを置けない。 縦、横、ななめのいずれかで同一色のキューブを先に3つ揃えた方が勝ち。 各アクションではキューブを置く他に各段を右方向または左方向に90度回転することも出来る。また、ケージの上下を反転させることも出来る。 お互いの手持ちキューブが無くなり、3つ揃えたキューブが無い場合は引き分けになる。 先に手持ちのキューブが無くなったプレイヤーは回転かケージの上下反転のいずれかを行う。 また、直前のアクションと同じまたは逆を行い、同一状態にすることは出来ない。(千日手の禁止) ■オンライン対戦時のルール 各プレイヤーは基本時間20秒と時間延長20秒が2回出来る。 ただしトータル10手ごとに時間延長が2回ずつ与えられる。 持ち時間が無くなった場合は負けとなる。
