Doge Miner 2

Doge Miner 2 rides the Dogecoin meme into a straightforward idle-clicker structure: clicking mines coins directly at first, but the actual goal is reaching the upgrade tiers that let mining continue productively even when you're not actively clicking at all.

Because each planet unlocks its own tier of upgrades, sinking every coin into maxing out the current planet before moving on usually pays off less than pushing forward once a planet's cheaper upgrades are bought, since later planets' base rates outscale a fully-upgraded early one. Letting the game run passively between visits matters more here than the clicking itself once idle income ramps up, treating it as a check-in game rather than a sit-and-click one gets more out of a session. Clicker Heroes runs a deeper version of the same idle-clicking progression if you want more systems to optimize.
