RollerCoin events: types and how to prepare

RollerCoin has events almost every week, some lasting a day, others a month. Each type calls for a different strategy. This guide explains the main ones and how to plan for each.
The events active right now, with the time left, are shown on the RollTheCal home page and update by themselves.
Spin event
You earn spins by completing event tasks, and each spin can give prizes, including miners.
- Before placing a miner you won, test it in the room simulator: a strong miner can push you to the next league by accident.
- If it has a bonus and you already have an identical one, the copy doesn't add the bonus again. See Miner copies don't add bonus.
Race event
A short contest, usually one day long, where points come from tasks and mini-games. Best for players who can play often during the period. Check the end time in the events box so you don't miss the final stretch.
Building (Grand Building)
A long event lasting weeks, where you collect resources little by little. Consistency matters more than one intense day: logging in every day usually pays more.
Burning event
You trade miners and racks from your inventory for progression points and Event Coins, up to 6 items at a time, and burning can't be undone.
- Burn copies and miners without bonus that no longer fit in your room first.
- Protect unique miners with bonus: losing their bonus usually costs more power than it seems.
Progression event
Points come from RLT spent, and a multiplier increases those points. Reward tiers get more and more expensive.
- Raise your multiplier before spending: it applies to every purchase after that.
- Calculate how many purchases you need for the tier you want and compare with the prize's value. Sometimes stopping one tier earlier is the best deal.
- Use the progression event calculator. Example: 218 million points with 1.99 RLT boxes, 1,000 points per RLT and a 114x multiplier take 961 boxes, about 1,912 RLT.
Seasons
Seasons last longer and bring new miners and prizes. When a season starts, it's worth reviewing your room: new miners can change the best combination for staying at the top of your league. Do it with the league calculator.
Checklist for any event
- Check how much time is left in the events box on the home page.
- Decide your goal before spending RLT or burning items.
- Test any new miner in the simulator before placing it in your room.
- After the event, run the optimizer again to get back to the top of your league.
