Logic levels · Move limit · No ads
A Flow Free alternative
with fewer levels, each one deeper.
Flow Free has been the connect-the-dots classic since 2012: pair every color, fill every cell, move on to the next board. More than 2,500 free levels, Daily Puzzles, and a Time Trial make it an easy habit, and it has earned its 4.8 rating from about 405,000 App Store ratings. Millrace is a different logic puzzle for the same kind of player. Each of its 64 levels gives you a move limit, a fixed queue of arriving tiles, and one exact number to build on the marked cell. You can lose in two ways, every level has a proven shortest solution, and there are no ads.
How does Millrace compare to Flow Free?
Both are logic puzzles with a definite answer. Flow Free gives you a very large number of short, relaxing boards; Millrace gives you 64 longer problems where the order of your moves matters.
What you do on a level
Millrace: Slide the tiles, and equal tiles merge. New tiles arrive one at a time at the arrival cell. You are steering toward one exact number, say exactly 64, on the marked cell.
Flow Free: Drag a pipe from each colored dot to its partner until every cell is filled. Pipes can't cross, and drawing over one breaks it.

How much there is to play
Millrace: 64 levels in six chapters, plus Freeplay, an endless board, and a Daily Challenge with the same board for every player.
Flow Free: More than 2,500 free levels across board sizes and packs, new Daily Puzzles every day, paid packs on top, and four spin-off apps.

How a level can go wrong
Millrace: Each level has a move limit and two ways to lose: block the arrival cell so the next tile has nowhere to land, or build past the target. Undo inside a level is free, and you can retry as often as you like.
Flow Free: Free Play has no move limit, and a wrong pipe is simply redrawn. Time Trial adds a clock when you want pressure.

Knowing you solved it well
Millrace: The result card shows your move count, your best, and the best possible: the shortest solution, proven by a breadth-first solver before the level shipped.
Flow Free: Counts your moves and asks you to use as few as possible, so every board has a clean-solve goal.

About Millrace
Questions
FAQ
What is a good Flow Free alternative?
Millrace, a tile logic puzzle for iPhone and iPad, if you want fewer levels that each ask more of you. Flow Free gives you more than 2,500 free connect-the-dots boards. Millrace gives you 64 levels, each with a move limit, a fixed queue of arriving tiles, and one exact number to build on the marked cell. It is free, with no ads, no account, and no tracking. If you simply want more Flow Free, the same studio's Bridges, Hexes, Warps, and Shapes apps are the natural next step.
How is Millrace different from Flow Free?
Both are level-based logic puzzles with a definite solution, but the work is different. In Flow Free you draw a pipe between each pair of colored dots until every cell is filled, so the question is where each pipe goes. In Millrace you slide the tiles, equal tiles merge, and new tiles arrive one at a time at the arrival cell, so the question is what order to do things in. Millrace also has a move limit and two ways to lose: block the arrival cell, or build past the target.
Does Millrace have as many levels as Flow Free?
No. Flow Free has more than 2,500 free levels, plus paid packs and new Daily Puzzles every day. Millrace has 64, in six chapters from Warm-up to Mastery. Every level was found by search, not drawn by hand, and a breadth-first solver proved its shortest solution before it shipped. For open-ended play there is Freeplay, an endless board, and a Daily Challenge that gives every player the same board each day.
Is Millrace as relaxing as Flow Free?
Not in the same way. Flow Free is built for unwinding: Free Play has no move limit, and a wrong pipe is simply redrawn. In Millrace you can undo freely inside a level and retry it as often as you like, but each level has a move limit and can be lost, so it feels more like a small problem to think through than a board to clear. If you want to unwind with quick boards, Flow Free is the better fit.
Does Millrace have ads or in-app purchases?
No ads. The whole game is free, including all 64 levels, Freeplay, the Daily Challenge, Hint, and coaching notes. The optional purchases are theme packs ($1.99 each, or $5.99 for all sixteen paid themes), undo bundles for Freeplay from $0.99, and a tip. No level needs a purchase, and undo inside a level is free. Flow Free is also free but shows ads; on the US App Store, a $4.99 purchase removes them and unlocks all packs.
Is there a version of Flow Free without ads?
Yes, two. In the regular app, the $4.99 Unlock All Packs and Remove Ads purchase removes ads. Big Duck Games also publishes Flow Free+ on Apple Arcade, which comes with an Arcade subscription, has no ads or in-app purchases, and carries a Data Not Collected privacy label. Millrace is a different puzzle, not a Flow Free edition, and it has no ads at all.
