What a good break puzzle looks like
A puzzle you open between two tasks has to respect the ten minutes you give it. It should load in a second, have one rule you already know by level two, remember exactly where you stopped, and get harder on a curve you can feel. It should never make you wait for energy, watch an ad or create an account. Both TabSpawn puzzles were built to that brief: they are plain HTML5 canvas games, they save progress in your browser, and they play with a tap on a phone or a click on a laptop.
Arrowscape: one rule, sixty boards
Tap an arrow and it slides the way it points until it leaves the board or bumps into another arrow. Clear every arrow and the level is done. That is the whole rule, and the whole game is the order. A blocked arrow will not move at all, and an arrow that only travels halfway can box in two others, so the question on every board is which piece goes first.
There are sixty boards in six worlds, from a 4x4 meadow with three arrows to a 9x9 nebula with thirty-one pieces, and from the third world onward some pieces are bars one to three cells long. Every level is generated in reverse, placing pieces by undoing moves, so it is solvable by construction; candidates are then scored for how many steps are forced and how many decoys they contain, and placed on the ramp by that score. Finishing in par moves earns three stars. Undo is free, and the three hints per level cap you at two stars, so you can always get unstuck without being rescued.
Dotweave: connect every pair and cover every cell
Each board has pairs of coloured dots. Drag from a dot and a thread follows you through neighbouring cells to its twin. Threads never cross: drawing across another thread cuts it, and dragging back along your own thread unpicks it. The level is finished only when every pair is joined and every cell on the board is covered, which is the rule that turns a toy into a planning puzzle.
Sixty boards in six packs climb from 5x5 with four pairs to 10x10 with fourteen. Each one starts life as a random path that visits every cell exactly once, cut into pieces of at least three cells, so a full-cover solution is guaranteed to exist. You get three stars when the number of threads you drew equals the number of pairs, which means no false starts. Every connection chimes one note up a scale, and the last one resolves it.
How to get three stars
- Arrowscape: first find every arrow that can leave the board right now, then ask which of them is holding another arrow in place. Free the blockers first.
- Arrowscape: a half move is a tool, not a mistake. Sliding an arrow into another one can open a lane for a third.
- Arrowscape: work the corners early. Pieces that point into a corner have one exit and it closes fast.
- Dotweave: pairs on the edge usually want their thread to hug the border; the middle is for the long pairs.
- Dotweave: a single empty cell with one neighbour is a dead end. If you see one forming, the thread next to it has to take it.
- Dotweave: cutting a thread costs nothing but a star. Redraw early rather than forcing the last pair.
And when you want something faster
Stackrise is the other kind of break: a sliding block, one tap to drop it, the overhang falls away, and the tower gets thinner with every slip. It takes a minute per go and keeps a best score. All three games share the same player name and public Top 10, so you can compare stars and heights with everyone else without signing up for anything.
Questions
Do I need to sign up to save my progress?
No. Progress is saved in your browser on the device you play on. The player name popup is only for the public Top 10 and can be dismissed or changed at any time.
Do these puzzles work on a phone?
Yes. Arrowscape is tap-to-play and Dotweave is drag-to-play; both scale to a phone screen and work on Chromebooks and tablets.
Are the levels random?
No. Each game ships a fixed set of sixty levels, the same for everyone, so star counts on the Top 10 are comparable.
Are there ads or purchases?
No. The games are free, with no ads, no energy timers and nothing to buy.
