Define an original block puzzle brief

Many block puzzle briefs start as "like that famous one, but with my theme". That gives a studio a reference point and leaves almost every real decision open. It also pulls the design toward the parts of the reference you are not allowed to reuse. A better brief describes the game from the board up, so it can be built, tested and judged without pointing at someone else's product.

Six things need an answer: the board, the pieces, the placement and clear rules, the feedback for every action, the fail and continue moment, and the identity (name, art, sound). The general mobile game brief template covers audience, monetization and launch; this guide covers the parts specific to block puzzles.

Write the prototype so that someone who has never played a block puzzle could sketch it. Numbers can be provisional; the studio will tune them during the playable checkpoint. A readable description looks like this:

Then list what you are leaving to the studio: exact grid size, piece weighting in the generator, score values and the continue rule. Flag the things you care about strongly, such as "no timer" or "must be playable one-handed", so they survive tuning.

Block puzzles live on feedback. The rules are simple, so the feel of each action is what players remember and what your ads will show. A matrix like this one turns "make it satisfying" into decisions a developer and an artist can build and you can check at the playable checkpoint.

Two columns are worth adding for your own brief: an accessibility note (colorblind-safe shapes or patterns, a reduced-motion option) and the ad moment each row could become. The multi-line combo and the near-full-board rescue are the moments our example concept uses for store screenshots and video ads.

The best known US case is Tetris Holding v. Xio Interactive (District of New Jersey, 2012). According to the Wikipedia summary of the ruling, the judge treated the gameplay rules of Tetris as unprotected ideas, but found that the clone Mino copied protected expression: the look of the pieces, the board and the overall look and feel. The court also found that Mino's marketing, which used the same color and style of pieces, infringed Tetris's trade dress, and Mino was permanently barred from distribution. The decision binds only that district, though other courts have cited it in clone disputes.

Apple's App Review Guidelines say the same thing in store terms. Section 4.1, titled Copycats, asks developers to come up with their own ideas and not to copy a popular app or make minor changes to another app's name or UI. What follows is practical guidance from a producer, not legal advice. Have a lawyer check your name, logo and store listing before you launch.

Identity does most of the work of keeping a block puzzle original, and it also sells the game. Our example concept makes three choices that no reference game dictated: beveled jewel blocks on dark velvet, clears that bloom into flowers and light, and a relaxed Zen mode with a sakura theme. Each one changes the screenshots, the ads and the feel of a clear without changing the rules.

• Pick a material for the blocks: glass, wood, fabric, candy, stone, light.
• Decide what a clear turns into: petals, sparks, water, confetti, notes of music.
• Choose a setting the board sits in, or decide that it floats in nothing on purpose.
• If you have a brand or audience, use its colors and voice, and keep them consistent from icon to results screen.

One board, one rule and one mode fit the $499 Core Game package; the block puzzle game page shows the example concept and what the build includes. If your brief has grown a level mode, a map or a coin economy, read the block puzzle cost comparison before you decide. If you are still choosing between puzzle formats, the puzzle games page lays them side by side, and the game idea quiz gives a quick read on which package fits.
