Math Raiders is a boss-battling game that builds math-fact speed: your child answers a stream of addition, subtraction, multiplication, or division facts to deal damage, and faster correct answers hit harder. It adapts to each child; facts they find tricky come up more often, and it tracks mastery of every fact.
How to log in
Apps in TimeBack log in automatically as standard. If the automatic login doesn't work, follow the steps below.
You can sign in with the TimeBack login button; there's no separate account or password.
Open TimeBack: Open "Fast Math - Math Raiders" from TimeBack on the “Home Page.”
Sign in to Math Raiders: You will be auto-logged in. If you are not, click the TimeBack login button - no separate account or password needed.
Pick how to play: Choose Quick Play to jump into a ~2-minute raid, or Mastery Trials to fight a chosen boss and climb the ladder.
How a raid works
A math fact appears (like “7 × 8 = ?”); your child types the answer as fast as they can.
A correct answer damages the boss; the faster it is, the more damage. A wrong answer is blocked (0 damage), and the correct answer is shown for 2 seconds before they retry the same fact.
The raid runs about two minutes, until the boss is beaten or time runs out.
Answering fast several times in a row builds a combo streak; a slow answer resets it.
Two ways to play
There are two modes.
Quick Play drops your child into a ~2-minute raid where the boss's strength adapts to them; great for just jumping in and chasing a personal damage or speed record.
Mastery Trials is the progression path: eight bosses, each a bit faster than the last, where beating your child's grade-level boss earns Track Master status.
Both can be played solo or with friends; one player makes a room, shares a 4-letter code (like “FROG”), and everyone fights the same boss with their own facts at their own level.
How XP, ranks & assessments work
The play is the practice, and XP now comes from winning fights, not just time spent.
You earn XP only when you win a raid with at least 80% of answers correct. A raid they lose earns 0 XP, though the minutes they spent still show in Timeback.
Speed: A faster win earns more XP for the time spent, so quick, accurate play pays off most.
Quick Play is where most XP is earned. The boss is matched to your recent pace, so you should win most of these raids. This is where we want you earning the bulk of your XP.
Mastery Trial bosses reward only the first three wins, and the reward shrinks each time: the first win pays full XP, the second pays half, the third pays a quarter. After that, the boss is done, and losses don’t count toward the three. It’s there for progression, not for farming XP.
Behind the game, Math Raiders tracks every fact; the Mastery Grid colors each one Gray → Cyan → Purple → Gold as it gets faster, and a child's Rank (Bronze up to Legendary) reflects how many facts on the track are mastered.
When they're fast enough to beat the grade-level boss, or hit the grade's speed target in a Quick Play raid over 90 seconds, a “ready for assessment” banner sends them to AlphaTest to take a test that formally passes the track.
Habits that lead to success
Answer from memory; the goal is instant recall, not counting on fingers.
Think first, then type; wrong answers deal no damage, so speed only counts when you're right.
Play about 10 minutes a day; short daily sessions beat long, occasional ones.
Watch the Mastery Grid turn facts from gray to gold, and your rank climb.
Raid with friends; share a room code and take down bosses together.
How to tell it's working
Good signs: moving up the boss ladder, facts turning Gold in the Mastery Grid, a rising rank, and the Speed Record Chart trending up. If your child is stuck on the same boss for weeks, the grid is mostly gray, or accuracy is consistently under 80% (so little XP is earned), it usually means the facts aren't solid yet, they may be guessing rather than recalling. Short, daily, focused raids are what move it, and the speed chart only counts raids of 90 seconds or longer.
Common Issues
How does my child log in?
Math Raiders auto-signs you in on TimeBack. You can also sign in with the TimeBack login button; there's no separate account or password.
Is this just a game, or real practice?
Both. The boss battles are built on real math facts; every correct answer is fact practice, the game adapts to the facts your child finds hard, and XP comes from raids at 80% accuracy or higher. The fun is what gets the hundreds of repetitions fluency needs.
The game shows a code and won't start a round.
That means the Multiplayer tab is selected; it's waiting for another player to join. To play alone, tap Solo at the bottom and pick Training Grounds, Quick Play, or Mastery Trials. (Training Grounds is always solo, so after one finishes, tap Solo again if the game jumped back to Multiplayer.)
If a button or feature remains unresponsive, check whether your child has met the necessary requirements, such as earning enough XP to unlock specific areas.
What is the “ready for assessment” banner?
It appears when your child is fast enough to pass their track, either by beating their grade-level boss in Mastery Trials (Track Master) or hitting the grade's speed target in a Quick Play raid over 90 seconds. It sends them to AlphaTest to take an assessment that unlocks the next track.
How do I read the Mastery Grid and ranks?
The Mastery Grid colors each fact by how well it's known: Gray (not yet), Cyan (learning), Purple (getting faster), Gold (mastered). Rank: Bronze, Silver, Gold, Diamond, Legendary, reflects the share of the track's facts you've mastered and appears on the Profile tab and Leaderboard.
What is Cindermaws Lair, and why is it locked?
Cindermaws Lair is a special area within the Fast Math section of Math Raiders. To unlock it, your child needs to earn 50 XP through gameplay after the door appears. XP earned before the door becomes visible does not count toward this requirement. Until they meet this requirement, the "What’s inside?" button will remain unresponsive. This is expected behavior and indicates that the feature is locked.
