Box Grinder

description

Box Grinder is an idle/incremental game about opening boxes and collecting rare items. Open more and more boxes, buy upgrades, and unlock new ways to beat bad luck.

generative ai disclosure

We have used generative AI to create reference images of Promo materials, which were later redrawn by an artist, and for creating item frames. We are also utilizing several assets that contain UI images that were created using AI and edited by hand afterwards.

Major demo update.

Thanks to your feedback, we've gained a clearer picture of the direction the game should take — which required rethinking and reworking quite a few things. This version of the demo implements a part of that. Thank you for your feedback!

Key changes:

• Backgrounds now grant bonuses, they need to be unlocked and can be selected.
• More chests (now 6), rarity distribution across chests has been rebalanced.
• Collection rewards reworked — stat bonuses removed, all rarities now unlock mechanics instead.
• Objectives replaced with Achievements, tracking functionality is preserved.

New mechanics:

• Once you complete your first collection, duplicates of that item will lower its drop chance — passively increasing the odds of finding new and rarer items.
• Auto-opening for unchosen chests, at half speed and without the ability to receive new items.
• Active abilities that grant a timed bonus, activated at a resource cost.
• Copy synergy — if 2+ identical items drop from a single chest, they combine and multiply the item's reward (e.g. 3 copies = ×9 reward).

New upgrades:

• Guaranteed lucky chest every X openings.
• Chance to receive an extra item per copy (after unlock Copy synergy).
• Ability duration.

More:

• Full rebalance of upgrades and costs, Storage rebalanced.
• Added option to show the resource cost of upgrades.
• Added option for chest drop sound volume.
• UI improvements.

This is a significant overhaul of the core gameplay loop, so unfortunately save progress from the previous Demo version could not be carried over.
