Crosswords & Scanwords: Russian Crossword Puzzle App Source Code for Android (25+ Formats)

Crosswords and scanwords are one of the most popular pastimes across the Russian-speaking world, from Russia and Ukraine to Belarus and Kazakhstan. The hard part of building a puzzle app is not the grid engine; it is the content. Writing thousands of good clues and grids takes years, and a puzzle app with thin content loses its players within days.

Crosswords & Scanwords is a Russian-language word puzzle app for Android that bundles more than 25 crossword, scanword and word-search formats in a single product, with thousands of ready-made, author-written grids. The seller reports that it has been live on Google Play for years, with over 100,000 installs and a 4.7-star rating from roughly 20,000 reviews, and that it is already monetized with ads and in-app purchases. For a buyer, that means an existing audience and a content library instead of an empty shell.

Features

25+ puzzle formats

• Classic crosswords in three difficulty levels, with a clue bar under the grid (e.g. "Famous English writer, 7 letters")
• Scanwords (Scandinavian-style crosswords with the clues printed inside the grid) in three difficulty levels
• Honeycomb puzzles on a hexagonal grid (7 variations)
• Estonian and German-style crosswords, five-minute crosswords and "by places" puzzles
• Vowelless crosswords, jumbles, keyword (number-to-letter) puzzles and jigsaw-style puzzles
• Fillwords (3 variations) and a "Believe or Not" quiz
• A crossword variant where answers are built from a circular letter wheel instead of a keyboard

Content

• Thousands of ready-made, author-written grids in Russian
• Clues written with humour, avoiding obscure vocabulary, so the app suits casual players as well as puzzle fans
• Dozens of formats to switch between, which the seller says keeps sessions long and brings players back daily

Gameplay and helpers

• A full on-screen Cyrillic keyboard with an answer-length box for the selected word
• Hints to reveal letters or words, with a visible hint counter
• In keyword puzzles, a helper places a guessed letter into every cell with the same number, so players don't need paper notes
• Zoom in and out and arrow buttons to move between words
• A help and settings menu, and a confirmation when a puzzle is fully solved
• A consistent night-sky visual theme across all puzzle types

Monetization already in place

• Ads shown during gameplay (AdMob)
• In-app purchases through Google Play Billing

Who it is for

• Android publishers running a portfolio of casual and word games
• Studios and entrepreneurs who want an existing audience instead of launching from zero
• Puzzle-content businesses looking for a ready distribution channel and monetization setup
• Buyers targeting Russian-speaking users, or developers who want to localize the engine into other languages

How it works

1. The player opens the app and picks a puzzle type from the main menu.
2. They choose a difficulty level and a grid.
3. They fill in letters using the clues, with the on-screen keyboard or letter wheel.
4. When stuck, they use the hints menu to reveal a letter or a word.
5. The app confirms when the puzzle is solved, and the player moves on to the next grid or another format.
6. Ads and in-app purchases generate revenue; updates ship through the Google Play Console.

Ways to monetize

The app already earns from ads and in-app purchases. A new owner could add a premium ad-free version, a subscription with new weekly puzzle packs, paid hint bundles, an iOS port, or translated editions for other markets.

Good to know

• Metrics are the seller's. Installs, rating, review count and revenue are reported by the seller. Ask for Google Play Console access or exports (installs, active users, ad and IAP revenue) before buying.
• Store listing transfer. Confirm whether the Google Play app listing (with its installs and reviews) is transferred to your developer account, or only the source code and content.
• Android only. There is no iOS version; an iOS port is a future opportunity, not part of the sale.
• Russian content. The grids and clues are in Russian. Selling to other markets means writing or translating new puzzle content.
• Market and payments. The audience is mainly Russian-speaking countries. Ad fill, Google Play payments and payouts in some of these markets can be affected by sanctions and platform restrictions; check how current revenue is collected.
• Accounts. You need your own Google Play developer and AdMob accounts.
• Content rights. Confirm in the agreement that the puzzle content and clues are fully owned by the seller and transfer with the sale.
