Mobile Free-to-Play

Sessions are built to run a few minutes and to end at a decision point. Attempts are rationed by an energy meter that refills in real time, so failing a level costs a life and eventually costs waiting. Purchases sell the removal of that wait, extra moves at the moment of failure, or boosts that resolve a stubborn level. A map screen tracks progress and shows where friends have reached.

King released Candy Crush Saga in 2012 across phones and a social network, refining mechanics that browser and social games had already established, energy systems and viral invitations among them. Hardware and payment infrastructure had just aligned: touchscreens everywhere, app stores holding a stored card, and a general audience that had never bought a game. Free entry was the only way to reach people who would not evaluate a price at all.

By revenue this became the dominant form of the medium, funded largely by a small share of players spending heavily. Measurement drives the design consequences, since every element is instrumented and tuned against retention and conversion, which favours legible loops and steady friction over authorial risk. Regulators have responded to spending by minors and to undisclosed odds, and several jurisdictions now require refunds, limits or disclosure.
