Swivia

Swivia is a true-or-false game played at thumb speed. A statement appears on a card: swipe right for Yes, left for No, up to pass, and the keyboard arrow keys do the same for those playing with a mouse. Each card shows its difficulty and the time it awards. The game banner holds only three counters: score, lives as hearts, and the current streak. The scoring scale is fully public in the instructions: 10, 20 or 30 points depending on difficulty, multiplied by the streak tier reached, and time is added for each correct answer. A round ends when the timer hits zero or when the three hearts are used up, and an end screen summarizes points, answers, accuracy and best streak. A challenge button is offered on the end screen, and the corresponding invitation screen promises the same sequence in the same order.

1. Start a round from the Play button.
2. Read the statement on the card and decide: swipe right for Yes, left for No, or use the keyboard arrows.
3. Swipe up to pass a question when in doubt: this doesn't cost a life, but it breaks the streak.
4. Chain correct answers to add time to the timer and raise the multiplier.
5. Collect the end-of-round summary, triggered by the timer reaching zero or by losing the three lives.

Swivia finds its rhythm in a rare design choice: time isn't a guillotine but a currency. Each correct answer earns seconds, each mistake costs a heart, and the pass buys safety at the price of the multiplier. As a result, the game relies less on general knowledge than on managing doubt, balancing the urge to decide quickly to keep the streak with the temptation to let a suspicious card go. The fact that the entire scale is displayed in the instructions (points, seconds, streak tiers, heart regeneration), makes it a fair scoring game, where the best result comes from an explicit strategy rather than a hidden mechanic.

Feedback is numeric rather than color-based, and the game explains it: a correct answer is worth 10, 20 or 30 points depending on whether the card is marked EASY, MEDIUM or HARD, and awards respectively 2, 4 or 6 seconds. The streak then applies its multiplier, ×1.1, ×1.5 or ×2 depending on the tier. A mistake costs a heart and resets the streak to zero, a pass spares the heart but still breaks the streak, and five consecutive correct answers restore a heart, never exceeding three. It's the counters on the banner (score, hearts and streak) that carry the information continuously.

Timed round

The game's sole format: true-or-false cards that continue as long as time and lives remain.

Challenge a friend

A Challenge a friend button appears on the end screen, and the corresponding invitation screen promises the same sequence in the same order to compare scores.

Leaderboard

A Stats button appears on the home screen, and the page contains a tabbed panel Daily, Weekly and Monthly alongside personal statistics.

• The pass is more costly than it seems. It doesn't use lives, but it resets the streak to zero and thus cancels the ×1.5 or ×2 multiplier you were building: on an easy card it's often better to decide by instinct.
• The timer caps at 60 seconds. Once the reserve is full, seconds returned by hard cards go up in smoke: it's time to speed up rather than play it safe.
• Hearts regenerate every five correct answers. A truly long round is therefore played by maintaining enough accuracy to recharge faster than you lose them, not by avoiding every mistake.
