Graphite Seam
A lamplit cut into the fell where the grey stuff comes out wet and shining. This is the world Nib leaves open to everybody on the front page, and its free round deepens the further it goes.
The long bench where cedar is grooved, filled and glued shut in pairs, with red shavings curling off the plane. An even-handed machine whose wilds stay clamped where they land.
The games are free and always will be. The account keeps your 100,000 coins, favourites, level and daily missions between visits — and lets us confirm you are 18 or over before you spin.
Virtual coins only. No real-money gambling, no prizes of real-world value, no in-app purchases. 18+.
Cedar Slat Line is the world most players settle into once the account is open. It pays a little more often than the seam does and asks less patience for it, which suits an hour meant to be quiet. Every Slat Crest wild that lands clamps to its place while the reels around it turn again for nothing; land another during that respin and the whole arrangement holds once more. Three Hand Clamps anywhere open ten free spins paying double, four open fifteen, and all five open twenty-five.
In the Clamp. A wild that lands stays put for one respin, and every respin that brings another wild buys itself one more, so a good pairing can be held for several turns.
Everything here is played with free virtual coins. There is no real-money gambling, nothing you win has real-world value, and there are no in-app purchases. Results come from a random number generator; past spins never affect the next one.
Measured by running this page's own engine for 5,000,000 spins: coin RTP 97.1%, hit frequency 45.3%, free spins about once in 115 spins, a win of 10x your stake or more about once in 99 spins. Coin figures only — no money is staked or returned.

Spin. The Slat Crest wild covers for everything on the bench except the Hand Clamp.
Any wild that lands stays clamped for one respin, and a fresh wild during that respin buys another.
Players after an even, undramatic machine with one clear extra to follow and no long silences to sit through.
Frequent small returns and a steady middle. The respins do the work here, and a run of three or four clamped wilds is the usual high point of a session.

The five card ranks (10 to A) pay the least. Three Hand Clamps anywhere open the free round. Full values for three and four of a kind are in the paytable.
One respin, and then another for every new wild landing during it. In practice a good pairing holds for two or three turns and occasionally longer.
It is worth having, though the machine is not built around it. Three clamps open ten spins at double, and the round sits on top of the respins rather than replacing them.
Because it asks the least patience. The seam is moodier and the racks are louder; the bench pays little and often, which is what most evenings actually want.
Missions reset every day and work across every world. They are optional.

The finishing room, where blanks go down into yellow lacquer and come up dripping into the racks. The highest-strung world in the works and the one that pays longest when it goes.
