孩子和電腦對手「小狸貓阿狸」玩暗棋：棋子全部蓋著，每一步可以翻開一顆，或移動、吃掉對方的棋子，把對方吃光就贏。三關從 8 顆棋子的小棋盤（只有大吃小）、16 顆（加入「兵卒可以吃帥將」），到完整的 32 顆暗棋（加入「炮要隔一顆才能吃」）。前兩關的棋子角落有大小數字，第三關可以自己打開或關掉。也可以兩個人在同一台裝置上輪流下。
會被吃的棋子會亮橘光，可以吃的棋子會亮黃光，幫孩子養成「先看危險，再想機會」的習慣。阿狸不會偷看蓋著的棋子，強弱會跟著孩子的程度調整，家長也可以在家長專區固定程度。這款放在奇玩星的「動腦休息區」，不是數學遊戲，不算每日任務和課綱進度。免費、無廣告、不用註冊，沒有線上對戰或聊天。
陪玩小提醒：學會之後，拿出家裡的象棋和孩子玩一盤真的暗棋吧！
Children play banqi, the hidden-piece game played with xiangqi pieces, against Ali the raccoon dog. All pieces start face down; each turn you flip one, move one, or capture, and you win by capturing all of the other side’s pieces. The three levels grow from 8 pieces (bigger captures smaller), to 16 (the soldier can capture the general), to the full 32-piece game (the cannon captures by jumping exactly one piece). Rank numbers on the pieces help on the first two levels and can be switched on or off on the third. Two players can also take turns on one device.
Pieces in danger glow orange and pieces you can capture glow yellow. Ali never peeks at face-down pieces, adjusts to your child’s level, and you can fix the level on the parent page. It lives in WonderPlay’s Brain Break corner: it is not a maths game and does not count towards daily missions or curriculum progress. Free, no ads, no sign-up, and no online play or chat.
