Random Bonus Events

Timed clickable bonuses that appear at random intervals and grant a short production or click multiplier — the mechanic that makes players keep the tab focused.

Why deferred: Real engagement value, but it needs buff state the game doesn't have (temporary effects with expiry interacting with the effect engine) plus art/sound. Milestone achievements have shipped, but the mid-game still has little to spend bursts on while upgrades exist for only 2 of 19 buildings.

Revisit when: all-building upgrades has shipped, making active sessions rewarding enough to boost.
