Varpeli Raft

Step one: tap a woodpile to lift its top billet.
Step two: tap the pile where it should land.
Step three: check the raft, because it has started to lean.

Varpeli Raft is a sorting puzzle set on a log raft moored on a Finnish lake at white night. Billets of mixed timber are stacked in piles along the deck, and your job is to end with every pile holding a single kind of wood.

How a raft plays out

1. A billet can go onto an empty pile, or onto a pile whose top billet is the same timber. Four billets fill a pile.
2. Every timber has its own end-grain mark (dot, cross, ring, triangle, bar or diamond), so you never have to tell the woods apart by colour alone.
3. The piles stand along the raft, and weight on one side makes it heel. The gauge at the top of the screen shows how far. A move that would tip the raft past its limit is refused, and the logs creak to say so.
4. Shift the load evenly, finish the sort, and the raft is done.
5. Your move count is compared with the raft's par. Par or fewer moves, without a hint, earns three stars.

What is in 1.0.0

– Three lakes with ten rafts each. Tyyni Bay starts with three or four timbers and two spare piles, Kaisla Sound brings five timbers on a narrower heel, and Ulappa Reach puts six timbers on eight piles.
– Stars open the next lake: 12 for Kaisla Sound, 30 for Ulappa Reach.
– A daily raft dealt fresh each day, with a running count of the days you have sorted it in a row.
– Undo as often as you like, and restart a raft at any time.
– Three hints to begin with. Each raft you clear on par for the first time, without help, adds one more.
– A sky book of six skies over the lake, from white night to northern lights, opened by the stars you collect.
– Sound, haptics and a reduce motion switch that stops the screen shake, lake shimmer and raft bob.

Varpeli Raft runs with the network switched off, carries no adverts and sells nothing; stars, hints and your daily run are written to the phone and nowhere else.
