DAILY: one word per dispenser; targets bank themselves when spelled — no bank button. Ignored letters rotate only after you'd have time to reach them (the bar). Finished words convert their dispenser into a multiplier tile — drive over it while spelling a later word to arm it (once per word). Same puzzle for everyone.
FREE PLAY: build any words on the fixed board. All tiles arm by driving over them mid-chain, once per word: 2L/3L boost your next letter, 2W/3W multiply the whole word. Bank with double-tap, Space, or BANK. A ♥ turns up on a letter now and then — bank the word to claim the extra life.
SCORES: top five per mode are kept on this device, along with records for longest word, highest-scoring word, longest snake and more. Beat one and you enter initials — they default to whoever went last, so pass the phone around.
ARCADE: free play plus hazards. Letters carry pickups — ● speed, ❄ frost, ❦ shield, ✦ firefly (rare, sheds a word off your tail and keeps the score), ♥ heart (rarest — an extra life, up to five). You carry pickups until you bank — lose the chain and you lose them. ☠ skull tiles and NEMESIS cost a heart unless a shield eats it. Skulls fade in for a moment before they bite, and nothing new ever appears in the lane you are driving down. NEMESIS grows on every letter it swallows; cut across in front of it and it dies, then returns at seven ten seconds later.
On a phone: swipe anywhere to turn the snake, and tap beside the head to steer it that way.
⌫ drops your last letter — your only undo. P pauses (auto on tab switch). ←↑→↓/WASD, drag anywhere, or click beside the head. Enter restarts.
