👆 Tide Pool Treasury

<p>Tide Pool Treasury drops you into a rocky tide-pool shoreline and dares you to build the most briny shells empire on the web. It all starts with a single tap on the pool: each press mints a little Shells, and Each rolling tide leaves fresh shells for your crabs to stash among the rocks.</p><p>Spend what you earn to hire helpers like Little Crabs, Busy Crabs and eventually Cosmic Crabs. They keep working even after you stop tapping, so your Shells ticks up every single second — close the tab and you'll come back to a tidy pile of offline earnings. Stack boosts such as the "pool Festival" to multiply everything, then chase achievements that hand you a permanent edge.</p><p>When growth slows, ascend to bank Tide Gems: each one you hold quietly supercharges all future runs, turning a slow start into an avalanche. It is built to play itself while you watch the counters climb, and it runs instantly in your browser on phone, tablet or desktop — no download, no sign-up. Fire up Tide Pool Treasury, find your rhythm, and see how big an empire shells can buy.</p>
