放置ゲーム（インクリメンタルゲームとも呼ばれる）は、プレイヤーが積極的にプレイしていないときでも進行する指数関数的な成長によって、ゲームの中でも特に中毒性のある体験を生み出します。最初はクリックしてわずかな通貨を稼ぎ、その収益を自動収入を生み出すシステムに投資します。時間が経つにつれて、受動的な収入がクリックの力を凌駕し、画面上の数字は数百から数百万、そして理解不能なほど大きな数字へと膨れ上がります。戦略的な深みは、どのアップグレードを購入するか、そしていつプレステージ（進行をリセットして永続的な倍率を得る）するかの選択から生まれます。Cookie Clickerがこのジャンルを確立しましたが、現代の放置ゲームは、コアとなるインクリメンタルループの上に精巧なテーマ、スキルツリー、進行システムを重ねています。ファンタジー放置ゲームでは自動化されたヒーローパーティーがクエストに出かけ、工場放置ゲームでは生産チェーンを最適化し、宇宙放置ゲームでは銀河を植民地化します。このジャンルはマルチタスクに最適で、作業中にバックグラウンドタブで放置ゲームを動かし、時々チェックして戦略的な決定を下し、天文学的な数字に驚嘆することができます。
