Free coin and mining games, reviewed one install at a time.
Independent reviews of free coin-merge and idle-mining games for Android, with real screenshots, honest pros and cons, and a side-by-side comparison table.
Two shelves, nine games
Start with a genre, not a list
Rather than one long catalogue, Thrumjoy is split into focused shelves. Each one only exists once there are enough comparable games to make picking between them worthwhile.

Editor's shortlist
Six worth your first install
A mix from both shelves — not a top six by score alone, but six that show the range of what is on this site.

Drill&Chill: Idle Miner Tycoon
Drill&Chill swaps the tap-a-zone structure most idle diggers use for a single fixed station: a hammer crushes ore into nuggets, a conveyor carries them off, and small customers roll up on scooters asking for a specific amount. It is a more concrete, watchable loop than most of this hub, undercut only by a top bar of icons the game never bothers to explain.

Coin Sort Merge Puzzle
Coin Sort Merge Puzzle uses the same wide, five-column tray as the rest of this hub, but adds a genuinely satisfying touch none of the others have: clearing a stack sends it into a glowing sphere that pulses with the merged number before settling. It is both the highest-rated and highest-scoring puzzle game in this hub.

Mine Rush
Mine Rush turns the idle-mining formula into a floor plan you can actually read at a glance: three marked zones, one lift, and a small crew that queues itself up without much input from you. It is one of the tidier idle diggers in this hub, even if the middle stretch repeats itself more than it should.

Pocket Sort: Coin Merge Puzzle
Pocket Sort gives you a wide, five-column wooden tray and a straightforward job: group the numbered coin stacks before the board fills up. It is the most spacious board in this hub, with short rounds and a daily-challenge hook that gives it a reason to reopen the next day.

ExoMiner - Idle Miner Universe
ExoMiner takes the idle-mining shape and reframes it as planet-hopping — an astronaut works an alien world until it is time to launch toward the next one. The sci-fi setting is the most visually distinct thing in this hub, even if the game underneath is a fairly linear chain of unlocks.

Golden Merge
Golden Merge opens on a pastel coastal cottage scene, cheerful in a way none of the other three puzzles in this hub attempt, before settling into a four-column board where most slots start locked and a "Next Target" banner steers your first several moves. It is the softest-looking game of the four, and the most hand-held.

Side by side
How the shortlist stacks up
We picked three games from each hub for this table rather than all nine, so it stays a genuine at-a-glance comparison instead of a wall of rows — the full nine are broken down on each hub page and in the ranked list below.
| Game | Genre | Typical session | Getting started | Offline progress | Editorial score |
|---|---|---|---|---|---|
| Mine Rush | Idle mining tycoon | 5–10 minutes | No tutorial screens — the three zones are labelled and self-explanatory | Yes — the active zone keeps working while you are away | 8.3 |
| ExoMiner - Idle Miner Universe | Idle mining tycoon | 10–20 minutes | Short intro that unlocks the first planet, then leaves the rest to explore | Yes — returns as a modest queue rather than a backlog | 7.9 |
| Idle Miner Tycoon: Gold Games | Idle mining tycoon | 10–15 minutes | Familiar elevator-shaft layout — little explanation needed if you have played one before | Yes — the lift keeps running and queues completed hauls | 8 |
| Pocket Sort: Coin Merge Puzzle | Coin merge puzzle | 5–10 minutes | No tutorial — the tray and Deal button are self-explanatory within seconds | No idle accrual — a turn-based board, progress only moves while playing | 8.1 |
| Golden Merge | Coin merge puzzle | 5–10 minutes | A "Next Target" panel points at your next move for the first several turns | No idle accrual — a turn-based board, progress only moves while playing | 7.2 |
| Coin Sort Merge Puzzle | Coin merge puzzle | 5–10 minutes | A short first round doubles as the tutorial, no separate instructions screen | No idle accrual — a turn-based board, progress only moves while playing | 8.4 |
Common questions
Before you install anything
Every game covered on this site can be installed and played from Google Play at no cost — that is the entry bar for appearing here at all. We do not track or write about what happens inside a game beyond that point; our reviews cover the core play experience, not billing.
We pick a small number of genres per catalogue and install every game that fits before writing anything, rather than working from a pre-decided list of "big names." A game earns a hub placement once there are enough comparable titles to make a genuine comparison worthwhile.
Yes. Every icon and screenshot on Thrumjoy is pulled directly from that game's official Google Play listing at the time of writing. We do not use stock photography or illustrations for game imagery.
Where a game has a public rating on the Australian Google Play listing, we show that figure and note when it was checked. Our own editorial score is a separate, clearly labelled number out of ten and reflects our opinion, not a copy of Play's aggregate rating.
We would rather cover a small catalogue properly than list hundreds of games thinly. Thrumjoy grows by adding whole genre shelves once there are enough games worth comparing, not by padding an existing one.
Yes — the contact page has a single email address for exactly that. We read everything that comes in, though as a one-person project we cannot promise a reply by a set deadline.
