The Games

- Block Stack — 堆疊的防守變體，其中每個未對齊的方塊都會削弱你的塔。在保持結構完整性的同時盡可能高地構建，對抗重力本身。
- Minesweeper — 通過推斷哪些方格是安全的來保護你的雷區。一次錯誤的點擊就結束遊戲。純粹的防守邏輯，磨練你的模式識別技能。
- Chess — 防守和反擊的終極遊戲。保護你的國王，同時摧毀對手的位置。掌握防守性棋局開局是需要終身學習的技能。
- Checkers — 建立防守陣形，迫使對手進行不利的交易。在這個經典策略遊戲中，位置良好的後排可以抵禦整支棋子軍隊。
- Tank Battle — 堅守陣地，保護你的領土免受敵方坦克的進攻。戰略位置和明智地使用掩護是生存的關鍵。
- Zombie Survival — 加強你的陣地，管理日漸減少的資源，並在殭屍群中生存。當不死的敵人不斷來臨而物資稀少時，每個決定都很重要。
- Asteroid Miner — 在收集寶貴資源的同時，保護你的採礦作業免受小行星撞擊。在威脅來自四面八方時平衡進攻和防守。
- Hex Puzzle — 通過將六邊形碎片拼在一起而不留下空隙來保護你的棋盤空間。一個防守謎題，其中每個放置要麼拯救要麼毀滅你的遊戲。
