About this game

Caser is a case opening simulator for anyone who loves opening cases and chasing rare drops, with no real money involved.

WHAT'S INSIDE

• Cases from cheap to top-tier. Every case shows its full contents before you open it: every item and its exact drop chance.
• A free case for watching an ad. It opens with any balance, so you're never stuck if you run out.
• Open in bulk: one, two, three, five or ten cases at once, with a summary for the whole batch.
• Upgrade: put up an item, pick a pricier target and spin the wheel. The pricier the target, the lower the chance, and that chance is shown right on the wheel. The whole catalogue of over 4,400 items takes part.
• Case Battles: everyone opens the same case at the same time, and whoever gets the highest total takes every drop. Your opponents are bots, so it works offline, no other players needed.
• Inventory sorted by price or by date, with selling one by one or all at once.
• A feed of recent drops, profile statistics and your best item of all time.

FAIR ODDS

The odds aren't hidden in the rules or buried in fine print. A case's contents open with one tap, every item shows its chance, and the upgrade wheel shows the chance of the target you picked. Nothing is recalculated behind your back.

IMPORTANT

This is a simulator. The balance, the items and every number in the game are fictional. Real money is not accepted, not paid out and not won. Items can't be bought for money, sold, traded or taken outside the app. There are no in-app purchases.

Intended for adults.

ADS

The app is free and supported by ads. A video plays only when you tap the free case button yourself. A full-screen ad appears no more than once per session and never before your fifth case, and you're warned before it shows.

Thanks for the feedback! We've noted your point about battles with bots. Coins can't be bought — the game is free and runs on ads — but the daily gift, the safe and the free case help you climb back up.

What’s new

• Frames instead of prestige: three jewelry boxes with 18 frames. Drop one, put it on — everyone sees it: on the leaderboard, to friends, in duels.
• 4 more frames for your relic collection — an ouroboros among them.
• Anyone who reset prestige gets back everything they burned, plus the special "Prestige Veteran" frame.
• Offline mode is now much more generous.
• A Friends tab on the leaderboard.
• Fixes: the upgrade wheel after it stops, the Sell button in the drop window.
