About FireBox: Color Block Puzzle
FireBox is a color block puzzle: drop blocks onto a six-slot conveyor and match 3 or more of the same color. No level timers. The campaign plays offline.
Each level has a fixed block sequence. Tap an empty conveyor slot to choose where each block lands. Let it overflow and you lose the level, so every drop is a small logic puzzle you solve at your own pace.
Why FireBox is different
• No timer on any level. Take as long as you like to plan your next drop. (Lives refill over time.)
• Every level is proven winnable. All 180 levels are checked by a solver before they ship, without using a single booster.
• No doomed continues. A continue is only offered while the level can still be won, and it only buys room on the conveyor. As the game itself puts it: "It never finishes the level for you."
• Ads never interrupt a puzzle. Rewarded ads are always your choice, and a one-time Remove Ads purchase switches off the ads between levels for good.
• Offline puzzle game. The whole campaign plays without internet: on a plane, on the subway, anywhere. No Wi-Fi or login needed for campaign levels. Forge Trials, leaderboards, the Forge Market, purchases and rewarded ads need internet.
• Colorblind friendly. Every block carries its own shape as well as its color, always. A color blind palette, reduced motion and haptics controls are all in Settings.
How to play
• Aim: tap an empty slot on the conveyor to drop the block you are holding.
• Match: line up three or more blocks of the same color to clear them.
• Combo: chain clears on back-to-back drops to push your score further.
• Plan: break iron crates, fill the level goal, and never let the conveyor fill up.
Features
• 180 levels across eight forge worlds, from the Ember Halls to the Forge Eternal.
• Simple one-thumb controls: a conveyor puzzle game you can pick up in seconds.
• Win streaks that earn bonus boosters. Once a streak gets going, one lost level never wipes it out.
• Rebuild the Great Forge with the coins you earn, stage by stage, and win gems back as it comes to life.
• A daily reward and fresh daily missions every day.
• Ember, the little flame who cheers you on from the corner of the board.
• Free to play. Coins, gems and boosters can all be earned by playing.
The shop keeps the same promise
