One Shot Cascade

One tap.
The chain does the rest.

Every board has exactly one tile that clears it in a single tap. Find it before the clock runs out, and the next board loads. Miss, and the next tap costs you.

One Shot Cascade is a free one-tap chain reaction puzzle game for iPhone and iPad. Tap the right tile and it detonates — the blast sets off whatever it reaches, and the cascade rips across the board with no further input from you. There is no level select, no lives and no waiting: boards come one after another, the clock tightens, and the run ends with a score and one more reason to go again.

How it works

  1. Read the board

    Tiles point at their neighbours. One of them, and only one, starts a chain that takes the whole board.

  2. Commit

    One tap. There is no undo and no aiming — the chain resolves itself from wherever you started it.

  3. Beat the clock

    Time is the only resource. Clearing a board in one tap banks seconds; taking three spends them.

What it looks like

Six screens from a real run

The One Shot Cascade title screen: a glowing orange tile throwing off rays above the game's name, a personal best of 5,186, and a Play button.
Open it and go. No menu to work through.
A board mid-detonation: a wide block of yellow tiles lit up and spreading, with unlit blue arrow tiles below and ONE SHOT 17 across the bottom.
A seventeen-tile clear from a single tap.
A chain reaction crossing the board, orange tiles firing into blue arrow tiles, with a two times multiplier and five seconds earned on the clock.
Each tile fires the next. You only started it.
The results screen: Out of shots, a score of 443, a TOP 3 WORLD badge, boards cleared, one-shot percentage, deepest cascade of eleven waves, and Charge earned toward the Silver rank.
Where the run actually went.
The League screen showing the Silver II rank, progress toward Silver I, and the ladder of divisions from Diamond down through Platinum and Gold with their Charge thresholds.
Charge is earned every run and never lost.
The Career screen listing lifetime statistics — runs, boards cleared, one-shots, best score, longest chain, deepest cascade — above personal bests and achievements.
Everything the game has watched you do.

What is in it

Endless generated boards

No level select, no two runs the same, and every board has a real answer.

Global leaderboards

The top 100 runs worldwide, updating while you play.

The Charge ladder

Twenty divisions from Bronze to Diamond, earned a point at a time and never taken back.

League rooms

A small group of players climbing beside you rather than a wall of strangers.

64 achievements

From a first ten-board run to the ones you will only find by accident.

A career record

Every run, board, one-shot and deepest cascade you have ever set off.

What is not in it

Worth stating plainly, because most free puzzle games on a phone have all four:

No ads

Not between runs, not anywhere.

No purchases

Nothing is locked and nothing is sold.

No account

No sign-up, no email address, no login.

No connection

It plays offline, and the boards catch up when you reconnect.

Questions

Is One Shot Cascade free?

Yes. It is free to download, there is nothing to buy inside it, and it shows no advertising.

Does it work offline?

Yes, entirely. The game never needs a connection to play. Leaderboards are the one exception — they need a connection to update, and a ranked run finished offline is queued and posted the next time you are online.

Do I need an account?

No. There is no sign-up and no login. You can play the whole game, including the leaderboards, without creating anything or handing over an email address.

Is it on Android?

Not yet. The Android build exists and is in closed testing on Google Play, but it is not publicly downloadable. When that changes, the link will appear here.

How long is a game?

As long as you keep finding the tile — usually a minute or a few. There are no levels to unlock, no lives, and no waiting between runs.

How do I delete my data?

Uninstalling the app deletes everything held on your phone. To remove your rows from the leaderboards, email us with the player number from the game's settings sheet. Full steps are under Deleting your data.
