Every chance in Lock In 100, taken live from the same settings the app uses when you open a chest. Chests, keys and fragments are only ever earned, never sold. Chest odds are the same for everyone. They are never based on what you've bought.
Last updated . The numbers on this page update the moment they change in the app.
At a glance
- Every chest has a main item, and a regular chest usually adds a bonus find or two. A regular chest's main item is Rare or better 38.1% of the time.
- Guarantees: a Rare or better at least once every 10 chests. Mega chests are Epic or better, with a Legendary at least once every 5 Megas, and the first Mega you earn each week holds something new.
- Stars come in 1% of regular chests (about 1 in 100), and never in a Mega chest.
- Rest Days: a 4% chance on your first chest each day, and at least one every 14 days.
- Duplicates turn into fragments (1 to 50, by rarity) or a gift for a friend.
- Your progress toward each guarantee is in the Vault, under Your guarantees.
Part 1 of a chest
Main item
Every chest holds one main item. Regular chests open with a Silver Key, Mega chests with a Gold Key.
| Rarity | Chest | Mega chest |
|---|---|---|
| Common | 61.9% | Never |
| Rare | 25% | Never |
| Epic | 10% | 72% |
| Legendary | 3% | 25% |
| Mythic | 0.1% | 3% |
These are the odds of a single roll. The guarantees below then step in, so over many chests you get a little more Rare and Legendary than the table alone. In a regular chest, 15% of Common main items come as 3 fragments instead of an item.
Guarantees
- A regular chest always has a Rare or better at least once every 10 chests.
- A Mega chest is Epic or better. If 4 Mega chests in a row have no Legendary, the next one is Legendary or better.
- The first Mega chest you earn each week always holds something you don't have yet, as long as anything is left to find. If you already own everything at the rarity it rolls, it moves to the nearest rarity that still has something new (never below Rare). A week runs from Monday 3 AM to the next Monday 3 AM in your time zone, across all your packs, and it counts when the Mega was earned, not when it's opened. Any more Megas earned that week roll as usual: Epic or better, and a duplicate if nothing new is left at that rarity.
- Mega chests come from streaks: each pack (and your main challenge) earns one every time its own streak reaches 7 days in a row, then 14, 21 and so on. A Rest Day pauses a streak without counting as a day. A Mega opens with a Gold Key (5 Silver Keys); no Gold Key is ever given free.
- Mythic: a paid pack you don't own yet, chosen at random. If you already own them all, it's a Mythic collectible.

Part 2 of a chest
Bonus finds
Regular chests only. Mega chests hold their main item and nothing else.
How many finds in a regular chest
| Finds | Chance |
|---|---|
| 1 find: the main item only | 10% |
| 2 finds: the main item and a 2nd find | 85% |
| 3 finds, a triple: the main item, a 2nd find and a 3rd find | 5% |
The 2nd find
| 2nd find | Chance |
|---|---|
| A second item (rolled like a regular chest) | 10% |
| A pet treat once pets arrive (until then, 1 to 2 fragments) | 18% |
| 1 to 2 fragments | 72% |
The 2nd find is never Stars. When the main item is already fragments, a fragments 2nd find stays fragments only 25% of the time. Otherwise it rolls again among the other kinds, so two helpings of fragments in one chest is rare.
The 3rd find (a triple)
| 3rd find | Share of triples | Of all regular chests |
|---|---|---|
| 1 Star | 20% | 1% |
| 2 to 3 fragments | 80% | 4% |
Stars in a regular chest: 1% of chests (about 1 in 100), and only ever as the 3rd find of a triple. Mega chests never hold Stars.
There are no other surprises: what's above is everything a chest can hold, plus a Rest Day now and then (Part 3).
Part 3 of a chest
Rest Day bonus
On top of everything else in the chest, regular or Mega.
- The first chest you open each day has a 4% chance of a Rest Day.
- If 14 days go by without one, your next chest brings one for sure.
- A Rest Day you find waits in your Vault until you pick the pack that saves it. Each pack saves up to 3.
- At the cap: up to 3 found Rest Days can wait to be saved. Find one while 3 are already waiting and it becomes 5 fragments instead, which you collect in the Vault. Rest Days can't be gifted or bought.
Duplicate items
Get an item you already own? It waits in your Vault until you choose: gift it to a friend who doesn't have it yet, or take its value in fragments.
| Duplicate | Worth |
|---|---|
| Common | 1 fragment |
| Rare | 3 fragments |
| Epic | 8 fragments |
| Legendary | 20 fragments |
| Mythic | 50 fragments |
Shop pricing
