Why Mobile Games Have Daily Rewards and Login Streaks
ONI Games · Published
Daily rewards bring you back to a game, and they are designed to. How login calendars, streaks, daily quests and timed chests work, why some need the internet, and how to collect them without stress.
Mobile games have daily rewards because a game you open every day is a game you keep playing. A small gift for showing up turns opening the game into a habit, and players who build that habit are the ones who stay for months. That is the honest reason, and it is not a bad deal for you: you get free rewards for a few seconds of your time.
What to know: daily rewards come as login calendars, streaks, daily quests and timed chests. A calendar that does not reset when you miss a day is the friendliest kind. Check which one your game uses.
The four kinds of daily rewards
- Login calendars give a reward for each day you open the game, usually with a big one on day 7 or day 30.
- Streaks grow every day in a row and reset when you miss one. They are the most motivating and the most stressful.
- Daily quests ask for something small, like beating 5 bosses, and pay when you finish.
- Timed rewards refill on a clock: a free chest every 4 hours, a free spin a day, energy.
An example: Idle Ronin's 7-day calendar
Here is the login calendar from our game Idle Ronin, with the real rewards from its code:
Two design choices in it are worth pointing out. The calendar counts the days you claimed, not calendar days, so missing a day never resets it: you simply continue where you stopped. And day 7 is worth more than the first six days of diamonds put together, which is the classic way to make a week feel like something to finish.
Next to the calendar, Idle Ronin has six daily quests, such as defeating 150 enemies or 5 bosses, that fill a chest with 50 diamonds and 3 Unit Cores, five weekly quests with a bigger chest (300 diamonds and 10 Unit Cores), and a free supply drop every 4 hours.
Why games use calendars and streaks
Daily rewards are a retention tool, and developers measure them carefully. A few things they are built to do:
- Give you a reason to open the game on a day you might not have.
- Show you the rest of the game. A daily quest that asks for a dungeon run introduces the dungeons.
- Reward long-term players more. The big day-7 prize is aimed at people who come back all week.
- Make missing a day hurt a little, in the case of streaks, which is where they can tip from fun to pressure.
Why do some daily rewards need the internet?
Because a phone's clock can be changed. If a game trusted the clock, you could collect a week of rewards in a minute by moving it forward. So games check the time against a server before paying rewards that run on the clock. Idle Ronin does exactly this: its daily login reward and its 4-hour supply drop ask for a connection when they cannot confirm the time, and the rest of the game keeps working offline.
It also explains why a clock change can break daily rewards. Games that notice a jump often lock them for a day to be safe.
When does the daily reset happen?
It depends on the game. Many reset at midnight in your time zone. Games with rankings, where everyone must play the same day, often reset at a fixed time for everyone: the Daily Puzzle in our Block Brain starts at midnight UTC and is the same for every player. The game's help or the timer on the reward usually tells you.
How to collect daily rewards without stress
- Learn which kind your game uses. If missing a day does not reset anything, there is nothing to worry about.
- Tie it to something you already do, like your morning coffee, instead of relying on notifications.
- Do the quick dailies, skip the grind. Most daily quests take a few minutes. Ignore the ones that do not.
- Let the big streaks go. A streak is a game's way of making you feel you would lose something. If it starts to feel like a chore, breaking it is fine.
- Turn off notifications you do not need. You can switch them off per app in Android's settings.
FAQ
Do I lose my login streak if I miss a day?
In games with streaks, usually yes. In games with calendars, often not: Idle Ronin's calendar, for example, simply continues from the day you stopped at.
Why did my daily reward not appear?
The most common reasons are that the reset time has not come yet, the game cannot check the time because you are offline, or the phone's clock was changed.
Are daily rewards worth it?
Yes, if you play the game anyway. Over a month they add up to a lot of free currency. They are not worth opening a game you no longer enjoy.
