Downpour

Downpour is a fast mental-maths arcade. Arithmetic sums fall down each player's screen like raindrops, and players race to type the answer before a drop reaches the bottom. Miss one and it costs a life. It's noisy, competitive fun that turns the whole room into a race.

How players experience it

1. A synced 3-2-1 countdown starts everyone at the same moment.
2. Sums fall from the top. Things like 8 + 5 or 9 × 3 drift down the screen. The player types the answer, and the matching drop pops before it lands.
3. A drop that reaches the bottom costs a life. A little row of hearts at the top shows how many are left. Run out of lives and the player sits out the rest of the round and waits for the podium.
4. It gets harder the more you solve. Drops fall faster, and more of them appear on screen at once (up to a handful), so players have to scan and answer out of order.
5. The round ends when the timer runs out (or the host ends it early), and each player's result is banked.

On phones, players tap answers on an on-screen number pad; on a computer they can just type on the keyboard and press Enter. There's also a sound-effects toggle, and a reduced-motion mode that shows one sum at a time instead of the falling animation.

The presenter screen shows a live leaderboard that climbs as players solve sums.

Setting one up as a host

Downpour has no questions to write. Every sum is generated fresh, so you just set the difficulty:

• Operations. Choose which kinds of sums rain down: add, subtract, multiply, divide. Pick at least one.
• Numbers up to. The largest number that can appear in a sum. Keep it small for younger players.
• Lives. How many drops a player can miss before they're out: 1, 3, or 5.
• Round window. How long the downpour lasts (this is the activity's time limit).

Subtraction never goes negative and division always comes out even, so answers are always whole numbers.

Tips

• The more they solve, the more they score. Sustained solving pulls decisively ahead of a few lucky answers, so it rewards focus over the whole round.
• Match the numbers to the room. Small numbers and add/subtract make a friendly warm-up; throw in multiply and bigger numbers for a proper challenge.
• Fewer lives, more tension. One life makes every drop matter; five lives is more forgiving for a mixed group.
• Great as an energiser. Short and loud, it works well between heavier activities.
