Grub is a browser game in the style of Plinko where you manage a factory of lively, rubbery caterpillars. Each run turns into an exciting physics spectacle: the caterpillar segments bounce off pins, score points, and plunge towards the reward slots at the bottom.
Customize your board by placing pins in empty cells, increasing bounces and multipliers, buying more caterpillars, and unlocking auto-drop as you advance. The payout for each run is calculated as pin points multiplied by the slot multiplier (x1, x2, x3, then x2, x1 again). Riskier paths promise larger rewards.
It's incredibly satisfying to watch and interact: hits trigger visual and sound effects, critical collisions make a bigger impact, and progress is automatically saved. Level up, experiment with segment skins, and play in landscape mode — ideal for quick sessions or prolonged background gameplay.
Grub offers relaxing fun, unpredictable trajectories, and the thrill of turning chaos into coins. Open the game, tap, upgrade, repeat. Observe the wobbling chains, plan your pin layouts, and aim for the x3 slot to hit the jackpot. Send your first caterpillar on its journey and see where luck takes it.
How to play
To start a run in Grub, tap the field above the pins to choose a spawn point. Only available caterpillars from your pool can be launched; if you need more, purchase them in the upgrade panel.
As the caterpillar falls, it collects points on active pins. Add new pins to random empty slots and enhance existing pins by increasing their bounce force and point multipliers.
The five bottom slots have multipliers x1, x2, x3, x2, x1. The multiplier of the slot where the caterpillar's head lands will be applied to the points collected during that run. Final reward = pin points × slot multiplier.
Use your coins to buy upgrades like more caterpillars, faster auto-drop, and stronger pins. Keep an eye on your level and income in the top bar.
Adjust settings for pause, sound, and skins. Your progress is autosaved, so you can come back later. Pro tip: place central pins first and aim for the x3 slot. Play in landscape mode and use auto-drop to collect resources while watching.
