Seven towers. One clever city. Can you build your way to victory?

Build a shared skyline in SUMMITRI, a competitive card game where mental maths, spatial reasoning and smart planning work together. Designed for 2–4 players aged 10 and over, it brings a construction challenge to family game night.

Seven skyscrapers stand in a circle, ready to grow. Use Number, Shape, Time and Location cards to build at the right site, match the required footprint and add exactly the right number of floors.

Every turn brings a choice. Build now to claim points, or prepare your hand for a stronger move later. Watch the shared crane, keep an eye on your opponents and compete for valuable building stages and City Awards. The player with the most points wins.

How you’ll build

• Calculate: combine two Number cards using addition or subtraction to reach the exact total.
• Visualise: rotate shapes to match a building’s footprint.
• Navigate: use Time and Location cards to move the crane and select your building site.
• Strategise: complete stages, pursue City Awards and plan your next move.

Why families will enjoy it

A shared city makes every player’s decisions matter. The mix of calculation, visual puzzles and friendly competition gives children and adults plenty to think about together, while offering practice in mental arithmetic, spatial reasoning and planning.
