Dropstack

Dropstack is a falling-block puzzle you can pick up in seconds. Slide and spin each piece as it falls, complete full rows to clear them, and keep the stack low while the speed climbs level by level.

• Earn coins every run and spend them on permanent upgrades (slower start, extra preview, partial clears and more)
• Unlockable block skins: neon, pastel, retro and shadow
• Local best score and saves
• Plays in the browser on desktop and phone, with on-screen touch pads
