COLLIDE

COLLIDE is a daily puzzle game where your mission is to identify every meaning of a single short code that collides across countries, elements, airports, airlines, and more.

Short codes were invented independently by people who never spoke to each other. MD is Maryland, Moldova, Mendelevium, Doctor of Medicine, the Roman numeral 1500, and Air Madagascar. Your job is to tap every meaning the code represents, with nothing telling you how many are hiding.

• Each puzzle gives you one short code with multiple meanings across different categories.
• Tap every option on the board that matches the code exactly, letter for letter.
• Categories are color coded: countries, airports, elements, states, currencies, languages, airlines, abbreviations, and Roman numerals.
• Wrong taps cost you 10 points and 5 seconds, charged at the end so you never know which tap was wrong.
• Find every meaning with zero mistakes and your score doubles.
• The daily mode gives you 3 boards back to back with 60 seconds total. Bank time on codes you know, spend it on ones you don't.

The trick is knowing when to stop. The board never tells you how many meanings it's hiding. Deciding you're done is part of the game.

Why we like it:

• ✅That moment when you realize a code has six meanings instead of three is genuinely delightful.
• ✅You learn bizarre overlaps you never knew existed, like how BAH is both an airport and an Olympic code.
• ✅The doubling mechanic rewards confidence and punishes guessing in exactly the right balance.

Hint: Don't overthink the obscure categories early. Start with countries and elements since those cover the most common two and three letter codes, then branch out to airlines and airports once the obvious answers are cleared.
