Make your game app with BDK

Get paid for play and bring players back for the next round. Your web game becomes an iOS and Android app that sells coins and level packs through the store, buzzes with each move, shares a score with a challenge link, and calls players back when an opponent takes a turn. Rendering, controls and scoring stay in your game code.

01 / 05

Notification permission

Ask players about challenge alerts once they have played a round, not on first launch.

  • Show what a challenge alert looks like before the prompt appears.
  • Ask once a player has won a round and a rematch is on offer.
  • Send declined players to notification settings from the game's options screen.

Touch feedback

Give players feedback they can feel as they play.

  • Confirm a move with a short vibration.
  • Buzz when a piece lands or a tile matches.
  • Mark a level cleared with a stronger pulse.
  • Warn when the round timer is about to run out.

In-app purchases

Sell levels and coins through the store, with the purchase sheet players already know.

  • Sell a coin pack from the shop screen between rounds.
  • Offer a level pack or a character as a one-time unlock.
  • Grant coins only after the purchase is verified.
  • Restore permanent unlocks when a player moves to a new phone.

Share sheet

Let players take their results into the conversations they already have.

  • Share a personal best straight from the results screen.
  • Add a link so the friend can play the same puzzle.
  • Send it to whichever chat app the player uses.

Bring players back for their turn, a rematch or a new daily puzzle.

  • Notify a player when an opponent takes a turn.
  • Tell a player a friend has just beaten their score.
