Lantern Isles Boosters and Coins: Every Price and Every Free Coin

ONI Games · Published October 10, 2026

How the shuffle, bulb, finger, lightning and rocket work and what they cost, which booster is the best value, the free letters from the lantern ring and win streaks, how combos pay, and every source of free coins in Lantern Isles: Word Puzzle.

Coins buy boosters in Lantern Isles: Word Puzzle, and boosters reveal letters when a word will not come. This guide covers every booster, the free letters you get without spending anything, and every way to earn coins.

We make Lantern Isles, so every number in this guide comes from the game's code.

The five boosters

Booster	What it reveals	Price	Unlocks
Shuffle	Nothing: it mixes the letters on the wheel	Free	From the start
Bulb	One random letter	100 coins	Level 3
Finger	The tile you tap	200 coins	Level 4
Lightning	3 to 6 random letters	300 coins	Level 5
Rocket	The first and the last letter of a random word	200 coins	Level 11

You start with 200 coins and two of each paid booster. A booster you own is always used before your coins, and a booster only works when there is something left for it to reveal, so a tap is never wasted.

Which booster is the best value?

Per letter, the bulb and the lightning cost the same in the first 100 levels: 100 coins a letter. After that the lightning reveals more letters for the same 300 coins:

Levels	Lightning letters	Coins per letter
1 to 100	3	100
101 to 500	4	75
501 to 3,000	5	60
3,001 and later	6	50

The finger costs more per letter but puts it exactly where you need it, often on the one tile that cracks a long word. The rocket shows where a word starts and ends, which is usually enough to guess it.

Shuffle first

Shuffling costs nothing and does not end your win streak, so try it before you pay for a letter. A new order often shows a word you could not see.

Free letters

Lumi's lantern ring

Every word you find charges the ring around the wheel. Longer words charge it more, and a word found within 8 seconds of the one before counts double. A full ring reveals one letter for free: at a calm pace that takes 6 to 10 words, and about half as many when you find them quickly.

The charge carries over to the next level, and a ring that fills when there is nothing left to reveal keeps its letter for the start of the next level. After 20 seconds without a word the ring drains, but slowly.

The win streak

Solve levels in a row without a booster and your streak grows; the flame chip at the top of the level shows it.

Streak	Free letters at the start of each level
3 to 5	1
6 to 9	2
10 or more	3

Any booster ends the streak, even one you got for free. Shuffling, Lumi's hints and the free letters from the ring and the streak never do.

Lumi's hint

If you find no word for 30 seconds, Lumi flies to the first letter of an easy word on the wheel. Nothing is revealed and nothing is spent, so your streak is safe.

Combos

A combo is grid words found one after another without a wrong word in between. Each word in the row adds one coin more than the one before:

Word in a row	Coins for that word	Combo total
2nd	1	1
3rd	2	3
4th	3	6
5th	4	10
6th	5	15
8th	7	28

A wrong word starts the count again, while bonus words neither break the combo nor add to it. The coins are paid when the level is solved. On a guardian level they are doubled and 50 more are added, and an optional video doubles what the level paid. So think before you swipe: a long combo is worth more than a fast one.

Every way to earn coins

Source	Coins	How often
Combos	1 more for each grid word in a row	Every level
Bonus words	20	Every 50 bonus words
Firefly level	3 per firefly	Special levels
Golden word	4 per letter	Special levels
Guardian level	Combo coins doubled, plus 50	The last level of every island
Daily Challenge	25	Once a day
Month trophy	500	Every day of a month solved
Word of the Day	30	Once a day
Daily Gift	25, 40, 20, 60, 40, 80 and 150	A seven-day row
Lumi's Jar	2 per firefly, 60 when full	Full in six hours
Weekly League	300, 200, 150, 60 or 20	Every week
Club chest	60 to 1,000	Every week
Medals	40 to 150 each	67 medals
Lantern Pass	Coins or boosters on every tier	30 tiers a month
Holiday postcard	500	Every holiday event
Free coins in the shop	30 per video	5 a day

The 67 medals alone pay 4,785 coins. Our bonus words and dictionary guide lists all of them.

Out of coins

Tap the booster you want and you can watch a short video to get that booster for free. From level 21, if you are stuck with no bulbs and fewer than 100 coins, the game also offers a free bulb for a video, once per level. Videos are always your choice.

The shop

Real-money purchases are optional:

Coin packs of 500, 2,500 or 7,000 coins.
Starter Pack, once: 800 coins, 5 bulbs, 3 lightnings and 2 rockets.
No Ads, once: no more ads between islands. Reward videos stay a free choice.
Lantern Bank: every level you solve drops 15 coins into the bank, up to 2,000. Once it holds at least 300, one purchase opens it and gives you all of them.
Lantern Pass premium: a second, bigger reward on every tier of the current month.

What is the best booster in Lantern Isles?

From level 101 the lightning is the cheapest per letter, up to 6 letters for 300 coins. Before that it costs the same per letter as the bulb, the finger is best for one stubborn tile, and the rocket is the quickest way to guess a long word.
